New 06 GTO
MS4
prc .675 springs and retainers
TSP 7.425 pushrods
FAST 102/102
underdrive pulley
new for the goat
kooks 1" 7/8
off road x-pipe
magnaflow cat back
Volant CAI
My question is what would be the ideal heads to get me to 500 RWHP with my current parts?
As for heads idk, if this is your daily driver the MS4 cam seems a bit big for the stock motor size, not a great DD cam but if it doesnt bother you then its alll good.
