Default I know its been beat to death but. LS6 vs F.A.S.T with MS3

I have an 01 with a tuned MS3 in it right now with stock heads. Would I see any increase in power with a fast 90/90 or 92 setup right now with stock heads? Or should i spend that money elsewhere? Thanks guys.

you will see an increase, but are you seriously willing to shell out around a grand for around 10rwhp? if you had an ls1 intake i could see doing it, but Id look at heads first.

dont let me make the decision for you (I just bought a ported 92/95 to replace my 78mm intake..$1500) but ive got decent heads and cam on a 6.0 so that was definately a weak point.

Depending on how much you have to spend, look into buying some new PRC heads, id imagine after all is said and done it will be about the same price as it would cost you to do the same with the 5.3 heads you have.
