Hello everyone... I would like you guys to be
the first to know 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, they 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 January 1st. These heads will be sold
exclusively through Dr. J's Performance and Speier Racing Heads.
"I will be the
first to say they are bad ass and will make serious power on any combination
matched to them. I was very happy to see someone take the heads I designed and
do with them exactly what they where meant for. I designed the head so head
porters could take them to extreme levels of efficiency. I truly didn’t expect
it so soon but there it is! Bryce and Chad where instrumental in the, “Head
porter” version of the Profiler 23° head. They told me what they wanted and
needed and Profiler made it for them. Its now a standard part number."-
