I kinda thought the iron LQ4 head were not the same as the aluminum #317 models. I do know for sure the #317 are carbon copies of the LS6 heads ( D-shape exhaust ports the primary improvement ) but with larger combustion chambers ( 72cc vs 64cc ). I also read some literature that says don't bother with the iron heads. I will check my car rags later for more....
