317 heads!
well im trying out the 317 heads once i get a mild cam to go with em. So the .040 cometics correct? what bore size exactly for a stock 5.7L ls1?
was wondering, with 317 heads, .040 cometic gaskets and a 9.9-10:1 CR, and turbo of course... this would work well right with a decent mild sized cam. Im in torn between a few on here (TSP224R, TU1-225, and tick stage 1 turbo cam 226)

man... digging this one up outta the grave lol
Finally, I have settled on a cam SUM-8706 (226/230 .600/.575 113LSA) and running stock 317 heads with LS9 gaskets and pac1218 springs on my stockish ls1. I'll post an update when I finally get it all together lol Last I calculated the CR was about 9.8:1 if I remember right with unmodified heads, but with the summit cam, power will definitely be a bit different.
Anyone else have any updates on their 317 heads, cam, and gaskets, in relation to the amount of boost and driveability?

(Note: I realize this is an old thread ... just trying to put it out there.)
