Pretty sure the AirWolfs are Bryce's proprietary CNC port, as I mentioned in an earlier post he has a very clever 'signature' mod that I've also seen on some Top Tier Cup car heads.

The Ports are cavernous for a Standard gasket 340 and he whittles a lot of meat from the guide areas to where the valve pocket/bowl more closely resembles an old Dick Landy Pro Stock head I saw years ago.
