gto 243 heads ???? 
Seems high to me, I paid $300 for a fresh low miles set of LS2 heads. Now
if that money included uprated springs, retainers, etc. it would make more
sense. But plain stock takeoffs with no work done and nothing special, I'd
work on that price.

got some info on the heads he said they have yellow valve springs , have the triangle under all spark plug holes, and that he is pretty sure they are the sodium filled valves ??? how can you tell if the valves are sodium filled other than weighing them ???
You can't....
LS6: intake = 73 grams, exhaust = 65 grams
