L92 head parts

i was wondering what all you can reuse from LS1 heads to transfer onto the L92 heads. my new magazine says L92 bare heads are 175.00 each and 400 each for assembled but need better springs. also can you run these heads on a stock LS1 bore without hurting anything or are they big bore heads. also in the future i am torn between a 346 FI or 402 Fi. which setup would benifet for from these heads. the FI would be a FM76mm turbo

Yeah, you need the 4" bore at least, bigger will be better. None of the valves will carry over, and if i recall, they have offset rockers too.
