At this time do we know if more than the Dart head is available permitted by NHRA???
Also heard that the dart head do "not" make any more power than the GM heads, they are thicker and probably will not crack after porting. My head only cracked on the external part of the head above head bolts. Told because the head surface had to much angle milled.

Being one of the longest CS drivers, what ever after market company gets approved, the head for GM should remain 23 degrees. Would save some money in combinations, Intake and maybe pistons. Back when the class was created it was for what was available at the time(cast iron) in the 70's, modified eliminator days. For GM it was the 23 degree heads, I believe the turbo heads. MY opinion only.
