Our Summit Performance® headers are manufactured from mandrel-bent tubing for superior flow and greater horsepower. The headers feature a pressure-formed collector for a better flow rate and a jig-welded tube-to-flange plate for a perfect fit. They're made for off-road and racing use only. Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom-altered parts, then it is the installer's responsibility to verify fitment.

Special warning regarding Summit Racing® painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.

Can I just bolt these on a 1967 Chevy C30 or are there some modifications involved?

No modifications are needed but some applications to require an extra $10 bracket for the alternator.

Will these headers work with the DynoMax 89007 Dual Exhaust Kit? Need exhaust for my 86 C1500 asap. The DynoMax kit is a 2.25" dual exhaust kit, so do the reducers go down to that small?

The reducers are 2 1/2 OD might be able to Buy reducers and welded in

Answer This Question


I am slowly piecing together a 1986 GMC C2500 with VIN M 350 automatic. Has A/C and going to be replacing the heads so figured I'd do the headers at the same time, how much modification would be required to use the existing pipes through to the back until I get to that point?

Asked by SEAN on August 05, 2017


I had to cut 1 ear off of the compressor mounting bracket and build spacers for 1 stud
