AIR WOLF SPECS

Hello everyone... I would like you guys to be the first to now about the New Pro Filer CNC ported AIR WOLF sbc cylinder head, developed by Dr J's Performance and Speier Racing Heads. The AIR Wolf will be offered in two sizes a 220cc intake runner and a 245cc .550 offset rocker. Our main focus during the R&D process was to develop a head that would out flow the competition and have the optimum port velocity map. Right now we are putting the finishing touches on the 220cc head, the will be flow tested @ Profiler next week by Darin before we go in to CNC production. If everything goes to plan this is going to be one killer 23° head. We should be able to ship heads late October or early November. These heads will be sold exclusively through Dr. J's Performance and Speier Racing Heads.
