What heads are these?
I have a pair of ls6 heads with "D" shaped exhaust ports, and the casting # is B211. Are these the ones with sodium filled valves? BTW theres no # like this anywhere that I've looked. they have stamped #s as well if needed. THanks!

Re: What heads are these? (neckcrank)
the casting #'s are the same, as far as I know. I they are original, the 2001 LS6 heads have blue valve springs, and the 2002 heads have yellow spring. The valves themselves have painted dots as well, but I can't remember the colors.

There are yellow marks on the springs. How about the valves? Any way of telling if they are the sodium filled? I am reasonably sure the heads are original equipped.
