Wow! That's quite some head! The ports are sure large enough. It looks from the photos that the intake and exhaust ports are the same size but that the exhaust ports are positioned in a slightly lower plane in relation to the intake ports.

I'm guessing the head would be a great platform for an all out racing engine. But would the large ports be a problem with a typical street (or hot rod) engine that typically runs a lower RPM? I'm assuming they would be.

Regardless, I wouldn't mind getting my hands on one, or a new aftermarket aluminum version.
