SLP or larger Kooks headers for my 402 - how big of a gain will I see I already have the SLP headers, but I noticed Kooks are larger in diameter. Is it worth the extra $$$ for my 402 stroker. How much gain will I see?

We tested a head and cam car and picked up 15rwhp and 13rwtq with the Kooks headers over the SLPs. It will be more on a 402. Kooks offers 1-3/4" as well as 1-7/8" headers. We are a Kooks dealer. Contact me and I'll give you a great price.

But anyway, you can get Kooks with with primaries the same size or larger than your SLP headers. With your stroker, you would benefit from 1 7/8" primaries.
