Best Brands of Headers for Chevy 

There’s no denying that the headers industry has many big players. These aftermarket brands claim to sell high-quality parts at varied price points. I’ve researched Chevy headers, and I’ve found four brands tend to fulfill their promise on quality and value for money. 

Speedway Motors Headers

This family-owned enterprise was started in 1952 by “Speedy” Bill. This guy figured that he would make parts if he couldn’t find the correct aftermarket auto spares. While that’s how Speedway Motors got its start, every piece is professionally engineered to meet the highest automotive standards, including headers. 

Speedway Motors headers are meant to give your car a unique voice. Whether you want your Chevy to have a deep roar or a quiet rumble, you’ll find the proper headers to get the sound and horsepower improvements that come with Speedway Motors headers.

Types of Headers by Speedway Motors  

  • Block Hugger/Shorty: This design offers simple installation, especially where space is tight. They are ideal if your vehicle has little ground clearance. You’ll find shorty headers in hot rods since they clear narrow frame rails and are close to the engine. 
  • Crossover: These are also designed for small-block Chevy engines with 1-3/4″ primaries and 3-1/2″ collectors. 
  • Zoomie: Typically, these are upturned headers on each vehicle side. They have 1-3/4″ primaries and extra-thick flanges.
  • Fenderwell: These are primarily for big-block Chevy engines, drag cars, and gasser-style rods. 
  • Roadster: These headers are for LS1 engines with 1-7/8″ tube diameter. 
  • Full-length: This is the most common style consisting of a mandrel-bent tubing that runs from the exhaust port down to the engine compartment and then to the vehicle’s rear. A four-way collector caps them, and they have either a ball type or flat mounting flange connection. 
  • Mid-Length: These headers have longer primary tube lengths. Also, they merge into a four-way collector with a flange to fasten to the rest of the exhaust. 

I found the Speedway Motors Shorty Chevy 350 Headers the best for hot rods with a narrow frame. On the other hand, the Speedway Motors Boom Tube Headers for Chevy 350 are perfect for running medium and high horsepower engines.

Best Headers for Chevy 350/5.7 Vortec

1. Speedway Motors 9300101 Tight-Fit Shorty Chevy 350 Headers

Best Headers For Chevy 350

For those struggling to find headers that leave enough clearance, you will like the Speedway Motors 9300101 Tight-Fit Headers.

The Speedway Motors 9300101 Tight-Fit Shorty Headers for Chevy 350/5.7L Vortec bring noticeable horsepower and torque gains. These universal-fit steel tube headers are ideal for tight spaces, and they come with 1-5/8″ primary tubes and 2-1/2″ collectors. 

These shorty headers give your engine a slight boost in horsepower that is more pronounced in the 1950s and 1960s vintage trucks and cars. Also, since they have a small 4-inch distance from the flange to the outermost point, they will fit perfectly on hot rods with narrow frame widths. 

The headers come as a complete kit with 2-inch reducers, gaskets, and header bolts. Nevertheless, installing them is a two-person job, and you’ll need a little technical know-how on headers installation. However, these headers do not work with vehicles equipped with a cross member below the engine’s center two exhaust ports. 

You’ll find that they work seamlessly with most oil filter systems and starter/transmission combinations. Nonetheless, they don’t clear angle plug heads and clamshell motor mount in 1973 and newer Chevy trucks and cars. 

These headers feature a black corrosion-resistant coating. Yet, Speedway Motors notes that it’s better to strip this coating down and apply high-temperature header paint. The headers reduce wear and tear on the Chevy 350 by providing better heat management, thus prolonging the engine’s life. They provide better fuel economy since they eliminate the restriction of stock cast-iron manifolds by offering better gases expulsion. 

Pros

  • High-grade steel construction 
  • Fit difficult applications
  • Ideal for hot rods, 1950’s – 1960s trucks and cars
  • Feature oval exhaust ports to fit small-block Chevy heads

Cons

  • Reconfiguration of the exhaust in some vehicles
  • Paint peels during installation 

For those struggling to find headers that leave enough clearance, you will like the Speedway Motors 9300101 Tight-Fit Headers. These block huggers go into the tiniest spaces that you won’t need an additional joint for the steering shaft.

The Speedway Motors Boom Tube Headers are for higher volumetric efficiency. Street rods that don’t mind the loud sound will appreciate this model.

The Speedway Motors 9301700H Boom Tube Headers come in a Zoomie style for replacing stock header in Chevy engines equipped with standard port heads. These headers are ideal for street use as they give you a classic dragster look. You’ll like the quality and accompanying sound that tells you’re running a robust system. 

Speedway Motors 9301700H Headers have extra-thick flanges at 1-5/8″ and primary tube measuring 1-3/4″. These features give you a loud exhaust tone for hot rods. It’s best to add baffles since you can hear a rumble to them at full throttle, and the idle is quite booming. Just make sure that you don’t get ticketed in some states. 

As for installation, these are ready to bolt-on; no welding is required. Since they are designed for standard port small-block Chevy heads, they will not fit wide cars. You’ll appreciate that they feature a long-lasting steel construction coupled with an industry-grade ceramic coating. 

The AHC coating blends in with the steel and creates a hydrophobic protection layer. Thus, they will not suffer from rust and corrosion. Furthermore, the headers can resist dirt and grime that ruin the headers’ look. 

During installation, keep in mind that the furthest primary tubes will stick out 4.8″ at the first bend on the passenger side and 4.25″ on the driver’s side. 

Pros

  • Ceramic coated for superior performance
  • No welding involved
  • Offers beneficial pressure balance
  • Suitable for medium-performance engines 

Cons

  • Easy to get into trouble with the law regarding noise 

The Speedway Motors Boom Tube Headers are for higher volumetric efficiency. Street rods that don’t mind the loud sound will appreciate this model. Nevertheless, you can add baffles to get the performance of Zoomies without risking a ticket.

This set of brand new Southwest Speedy 440-2045 Shorty Headers will fit Chevy 350 engines in a tight application. The block hugger headers work perfectly with under-engine cross members and side mounts. You can use them in most engine swaps and when you can’t find a specifically designed header.

  • Accurate fitment 
  • Used alongside side mounts
  • Better fuel mileage

6. Schoenfeld 198A Conversion Headers for Chevy 350

Schoenfeld 198A Conversion Headers for Chevy 350/5.7 vortec bundle the best features, including conversion primaries to achieve full throttle response, engine efficiency, and better exhaust flow.

Schoenfeld 198A Conversion Headers for Chevy 350 are the classic recipe for horsepower. You can inject more horsepower into your Chevy 350 and push it to give you extra power. These headers exit at the front mid-fender or a fantastic-sounding car. 

I particularly like that you can order these headers with spread port, standard, or 18-degree flanges. The flanges are perfectly machined to sit perfectly on your exhaust manifold. In addition, the headers have a high-quality black finish. Although the paint is temporary, it prevents rust formation during transport so that you receive new parts. 

The primaries on these headers are 1-3/4,” and collectors measure 3-1/2″ x 8″. The primaries increase the airspeed, which comes in handy to scavenge the exhaust port systematically at low engine speeds. On the other hand, these collectors give you usable power across the whole power curve. You can expect an increase of 4 – 6 lb.-ft of torque, and low-end power may increase by 800 RPM. 

Schoenfeld 198A Conversion Headers can move serious air and increase total power gain. Nevertheless, since it’s for a 350 that never sees the other side of 7000 RPM, you may never see its true, top-end potential like if you were to install it in a high-performance engine. 

Pros

  • Offer plenty of clearance
  • Fit as they should 
  • Perfect-fitting flanges 
  • 16-gauge steel 

Cons

  • Sit an inch inside fenders instead of exiting fully
  • Temporary paint 

Schoenfeld 198A Conversion Headers for Chevy 350/5.7 vortec ensure maximum airflow for off-roading and racing performance. They bundle the best features, including conversion primaries to achieve full throttle response, engine efficiency, and better exhaust flow.
