Default Engine build

Hi all,
Just a quick q for you guys running 102 fast intakes on your stock block? Thinking about springing for the intake and NW 102 tb and 4" cai. My q is: what size heads should i go with this to make the best power with a decent cam and the 102 pkg? Heard anything from porting my stock 243's to 245's! Thought 245's need a bigger displacement (400+). Will they work on the stock LS2? Any help on this appreciated! BTW 05 GTO M6, 1 3/4 kooks, catback, 3:91, suspension work.

Probably depends on your budget. If $$$ is not a big deal then go with some AFR or TFS heads. If trying to do it on a budget I would say some ported 243's would make good power too. Could also go with some ported 5.3 heads for a small bump in compression to make a tad more power too.

wow I used to live in Hampton, maybe I know you? Was there 2001-2007 working at Langley AFB. And yes I wanna get in the 11 sec club!! Yes I like the AFR's but dont know which size 205, 225. 1 person suggested 245. Thought 245 would be too much for a stock 346? Money good right now so want the best.

L92 heads and the 102mm for the rectangular port heads.

Might even hit high 10's.. and it'll be extremely streetable.

There are sets of l92 heads going around for $500...
Cam/spring/pushrod package $625 IIRC
Head gaskets/ARP bolts - $250
L76 intake (you dont really need the fast, plus with this you can use your stock TB) $250

bang, 485RWHP.... Around $1500

In one post you said Ls2? another 346? L92's will work great on a Ls2 364 motor but will not fit a 346 Ls1-6 Bore.
