I'm looking for LS6/LS2 heads as cores. Anyone have an old set laying around?

Look on car-part.com in your area. I just picked a set of 243's for $300 yesterday.

Are the 5.3L 243 heads different from 6.0 243 heads? Smaller combustion chamber?

I thought the 5.3's had 799's

I look for 234's of a TBSS/GTO with the yellow springs or I know the CTS-V ones sometimes had the lighter valves.

I don't care about valves, springs, or any of the valvetrain. I am sending them to be machined and built...probably Advanced Induction, Texas Speed, or TEA.

I think 243s and 799s are identical, but I don't know for sure, or if there is a 5.3L version and 6.0L version of each.
