Magnum Head porting for the beginner, Pt II Exh

On exh flow ratio, theres ideal and then there is what works, then there is handicapped. You can be pretty far below ideal and make big power. There are ford BB heads that when full ported...are as low as 50% ..and make 900hp on 470+cid. Could it make more.. yes... but it's still making 900. A quiet non turbulent exh port is something not a lot talk about. That's important too. Maybe more so. Great thread, we needed one on these.
