4/7 Swap Headers

[kevpow]

When running an engine that has the 4/7 cam set up, do you have to run different headers? Thanks

Only if you are running a tri y headers

[FlatTire]

no. you can run tri-y or non tri-y with a 4-7 swap cam. The dyno will help you make the correct choice.

If you run tri-y headers, they have to be built for a swap cam. Conventional headers will work fine.

either way the numbers arent much different from conventional headers if you run std seq. tri ys.

if your asking will it hurt the engine the answer is no
