I may be changing directions on a project and will offer the heads

they are brand new LS3 GM #823 's complete with LS3 valves (L92 valves are different, but same size) springs, retainers, keepers and seals

Great price on the new shortblocks!!

We just built a LY6 for a buddies sandrail , stock bottom end w/ ARP rod bolts, Lunati cam/ springs/pushrods on L92 heads, LS3 intake w/ 96mm throttle body and a custom tune (on chassis dyno) it made 540hp @ at the crank!

540? What were the cam specs If you don't mind me asking?
