LS Series Valves
The LS6 & LS3 had/have the hollow stem sodiums, the LS1 did not. The LS6 & LS2 heads are extremely simular castings, the only difference being the sodium valving in the LS6 heads, with "yellow" valve springs, which simply denotes seat pressure.

7K rpms with the right combo. I would use the L92s on larger bore motors like a 383 or 402 or bigger.
