The intake was non ported stock out of the box!!!!!! . needless to say I was happy with the results. other mods are honker cold air intake, slp 85mm mass air ported 90mm tb, 1 7/8 lngtubes headers withx pipe /cats B&B catback. stock cam & heads still making good hp.
386 rwhp to 410 rwhp air to fuel ratio at 12.8 timing set at 26 to 28 degrees.

According to some literature that I was reading sometime ago the stock Ls2 intake has a lot of leak by and was poorly manufactured. GM switched it's manufacturing process with the LS3 intake to correct the issue.

I'll more than likely go with a cam with a 228/232 588 to 591 lift. I don't want to go any larger than that . As for the heads I am not sure,
2500+ for trick flows will hurt me deep, I will continue to do my home work, I only want to shell out 1500 at the most for heads.

Great gains with the intake! The bolt-on LS2 and LS3 cars are getting scary fast!
There's another thread here about the Trickflow heads right out of the box that made great power and went for around $1700.

I am not saying that you have to spend mega money on aftermarket castings, I am just saying to think about the context of what you are doing.

Well it's funny that you say that about going cheap on the cylinder heads but the company that I WORK FOR JUST announced that they will be laying off employee's
(Dow chemical) so needless to say all R&D funding has come to a halt
