LS6 head casting is the same but LS6 heads come with lightweight valves.
why not go with AFR or TEA,something with lots of people running them,you can get more feedback. if you buy a head because it's cheap,then you get a cheap head. i bought a cheap head a few years ago,then went to AFR's and gained 47 hp over the cheap head.on paper the cheap head seemed to flow just as good as my new AFR's. with a 47 hp gain,i don't think they did flow as good,you get what you pay for.

heads I bought the Stage III's with upgraded springs. They will be flowed as soon as their received (should be this week) so we can get a matching cam. I'm confident there will be no major difference but if there is, I'll let all know.

he was part of the CNC program design. I highly doubt they would sell
a head that doesn't perform. They are dedicated to performance. They
don't just sell parts mike. Besides, they've been on the flow bench and
the flow pretty damned well IMO.
I say give them a call and ask them about their heads...or swing by
the shop and ask them.

243 "casting" was develloped for the LS6 motor which was in the 01>04 ZO6 Vette.
LS6 carrying 243s 02>04 had lightweight sodium filled valves.
LS2 carrying 243s have standard solid stainless valves (these are the ones being used).

I run their Stage I LS1 (stock casting) heads and couldn't be happier with the results. My car picked up 100 RWHP with the addition of those heads, a 224/228 114 cam, headers, and LS6 manifold. I will soon be swapping these for the LS6 heads so it'll be interesting to see the results.
