World LS7X Heads on 346/383? Will it be possibe to get a set of these heads in a small bore set up to go onto a 346 or 383? Reason why i'm asking is that it would be much cheaper to get a set of these heads and an ls7 intake than it would be with a comparable set of ls1 heads with a fast 90/90. Or am i crazy and this wouldn't be a good idea or wouldn't work? 
Thanks
Thanks

oook.
soo, do the valves clear the bore or not?

Would they even be to much for 383? What i really want to do is use them on a 383 and then build another engine for a turbo or redo the 383 for boost. So wouldn't a turbo and/or a 383 be able to take advantage of the heads?

that would depend mostly on other variables, not just displacement...
ive never heard of anyone running any LS7/L92 style head on a smallbore block.. and i dont THINK it'll clear at all, but ive never actually measured, nor ive i read where anyone else measured.

98 Z28,
I'm not sure what the bore sizes are on the 346 and 383 combinations, but we do not recommend a bore smaller than 4.00" with our LS7X heads. The valve sizes are 2.200" x 1.625".

Thanks for all the info guys. The bore on the 383 would be just under 4. It's not to big of a problem right now i still have to figure everything else out before i even start thinking about building it.
