i am cammed and have headers and the shake and rumble does not create any fitment issues with my kooks.
some people have moved their engine slightly but i wouldnt recommend that unless they are not squared on the mounts. another fix people have used is to dimple the headers...again wouldnt recommend that.
what size headers and what brand? there are brands out there that wouldnt stand for improper fitment and will make it right or tell you how to.
