Our Summit Performance® headers are manufactured in the USA 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. Gaskets, mounting hardware, and reducers are included. 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.

Summit RacingSummit Racing Verified Purchase

bought these for my engine swap. the box arrived looking awful, big holes taped shut. Headers looked fine though. these went on a 76 gmc 4x4 with a 396 swapped in, and yes they fit fine even though it was a small block truck and I used the small block motor mounts. This is a 2 man job though. Nearly impossible to hold them up and start bolts in. with an extra guy, and it is pretty heavy to hold up, 15 minutes per side. Even with the MASSIVE primaries, they fit right in there no clearance issues at all. Paint did immediately burn off. ...read more

BBC headers

Summit RacingSummit Racing Verified Purchase

Installed onto 1986 Chevy C20, 454 BBC. Easy to install with a lot of free room to move around. The paint did blow off during the break in leaving some smoke. Other than that, no leaks and seem to work well. No longer back but a shade of gray.

Great headers for the money

Great fitment, priced affordably. Paint is actually standing up, have about 1500 miles on them and still look great.
