are you sure it's from the engine and not the headers?
is it in neutral or in gear when you bring it up to 3.5k? could be alot. more info please. pop your hood and have a buddy slowly rev it to 3.5k and listen to where the sound is coming from. i doubt it's detenation since your only at 3.5k unless you have an assload of mods and no tune.

it doesnt really matter who made the heads, but whether you have a tune or not. all of thise different mods, are going to change the way the car runs a lot, gonna change your fuel needs, and if there is not tune, your not getting the right doses of fuel and that is very dnagerous
