    Head/intake upgrades for stroker?

    Just getting into this LS1 stuff, so please explain any "common" abbreviations you guys use for technical stuff. I just bought a 2000 SS with receipts for about 26,000 in work/parts, and I'm looking to step it up even more. It's got a 382 (3.900 bore/4.00 stroke) Lunati 4340 crank and Lunati billet rods & 2618 pistons along with ported Z06 heads, a Z06 intake, SLP longtubes, and a cam that specs out at 232/234@.050 and 112+2.5. Lift is .647/.651 at the valve. It's got engine dyno results of roughly 590HP and 550TQ. Compression is 11.97:1. My main question is, has anyone gone from something like this to a set of the AFR 225s or one of the ET Performance heads and an LSX w/90mm? The car has timeslips of (spinning) 11.48@120+ with 60's in the 1.55 range at 3680lbs. with a 3200 stall and 3.73s. I'm hoping I can hit 550RWHP+ if I step up to the 225s and LSX90. Do you guys think it's possible? I'm also planning on a new cam, who does the best LS1 cams, and I heard Yank (SS4000 or 4400) converters were the shiznit. True? Thanks in advance!

    It would be tough to get 550 out of a 385 with its small bore..Right now your probably at 465-475rwhp? You wont be able to pick up 75rwhp..Maybe half of that. I have a good connection with Comp Cams.... I also have a Yank PT 4400 with 1.5 hrs on it (dyno time) that I don't need anymore.
