LS2 heads and intake to LS3
LS2 heads and intake to LS3 I've searched for 3 days and can't find info on this. Is it as simple as bolting on a set of LS3 heads and intake and throwing a cam in? Seems you could get the top end stuff for $700 or so as opposed to 3K for Trick Flows and a Fast. How much more is there to gain from the nearly $2500 price difference? Any insight is appreciated.
Use a thinner gasket and you'll get a nice compression bump too. Stay with a mild cam and you'll be fine and make good power.
Top end after market heads offer two things. The ability to squeeze the last 10 HP out and the ability to run bigger cams without cutting valve reliefs in the pistons. I've seen several guys post up the results using a 224/228 114 or 228/232 114 cam and getting 450 - 470 rwhp in an LS2 vette when swapping to LS3 heads and intake.
Porting the intake will be good for 5 - 10 HP with a cammed set-up.

Do I need different rocker arms, fuel rails, lifter? The Trick Flow heads require the use of aftermarket rockers if I remember correctly. I'm just trying to get the most bang for the buck, but I need a realistic idea as to what the swap will cost.

the ls3 uses a different map sensor bigger with a bigger hole in the intake, some people have used silicone to make the stock map fit. it also bolts down instead of using a clip.
Ya just trying to get an accurate idead of what is needed and I dont want to flycut pistons.Its between this or saving for Trick Flows and a ported FAST.
