Thanks guys. I am thinking about buying a set of there allm heads anyone know what the max flow is on these beasts? :cheers:
this is from there site.
Large, free-flowing intake and exhaust ports look nicer "out of the box" than most port jobs you'll find done to factory heads. Instead of casting the ports small (like the factory did) and having to port them yourself, we've designed the ports to flow out of the box, better than a "full race" ported factory head would. Port volumes are about 212CC's on the intake and 72CC's on the exhaust. Intakes flow about
280-290 CFM as cast, with the potential to reach at least
330 CFM or more with porting. Compare that to 215-220 CFM from even the best factory production heads such as 906's or even 915's! Larger 2.14" and 1.81" valve sizes also come standard. Combustion chamber is a "closed chamber" design, with quench area built in, so the benefits of running "tight quench" can be realized. Chamber size "as cast" is about 84cc's.
i have a set but i am waiting for the right project to use them. so they are still in the box.
