Question

LS6 vs. LS2 Heads?

What are the differences between LS2 and LS6 heads?

Aren't they both 243 castings?

05+ do not use lightweight valves, correct?

Are the valves the same length as the 02+ ZO6, just not sodium filled? If so, then the ZO6 valves would be interchangable?

The second part of the question would be, if they are the shorter LS1 type valves then the LS2 heads should bolt right on the a LS1 with a stock cam?
