quote:This is one area where the "high port" Cleveland heads is superior to the original Ford iron head exhaust port configuration which turns them down. The 2v ports simply can't be made to flow equal to the 4v ports in any configuration.
The 2v iron head is worse then the iron 4v in that respect.
That's one reason why the 3v heads, 2v intakes with 4v exhausts are popular.
I'm a little baffled by this. I've been hearing for years that the 2v exhaust port actually flowed better than the 4v exhaust port. The opposite of what you are saying ??
