P&P LS2 heads or 90/90
Mods are:
stock ls2 heads
F13
lid w/K&N
ASP pulley
Kooks LT's
kooks CYP
cutout
And cheeper also.
After selling your intake and TB it would probally be only about 800 out of pocket when you get some more money saved up to swap to the 90/90.
YOur heads are doing damn good looking at your numbers through the cats. Intake would be about 15hp or so if tuning is done after intake swap. Heads may give you more but then your car is down waiting to get yours ported. I plan to do better heads but I am waiting to pull the motor later in the year ( when cold air is gone ) to freshen up the bottom end. Intake is a 1 day swap for extra 15 hp that will benefit you later for future mods.
Your heads stock are about as good as my mild ported ls1 heads. I dont want to pull the heads untill the motor comes out .
