243 heads also came on LS2 GTOs and I got a pair of those
with silver springs. The 'vette version with the lightweight
exhaust valves may be different looking. I have not looked
at a Corvette LS6 head.
I wouldn't worry about it because you ought to upgrade
springs when you do a cam swap, and I reckon you will
someday.

.0236" longer than LS1 valves are the only LS6 heads. The LS2 6 liter engines
in the C6 vettes and GTOs as well as some aluminum 5.3 truck engines have
243 castings. The truck heads would have plain springs.

243s with the hollow stem intake and sodium filled exhaust valves which are
.0236" longer than LS1 valves are the only LS6 heads. The LS2 6 liter engines
