RE: OK, what subject? [n//m]

Well, this thread is about heads and ports so here's my 2 cents. And then give me your thoughts on my comments.

Dan is right about port size.

The second thing about these heads that make them different from the standard 390 head is the valve face/seat angle. The CJ head has a 30 degree intake valve face/seat which helps air flow at low lift but hurts high lift flow. But the CJ cam does not have the valve open at high lift for very long so the face angle becomes a non-issue with the stock cam. Valve seat/face angle has a impact that is dependent on valve lift. With a high lift after market cam changing to a 45 degree face (and seat) usually increases high lift air flow and decreases low lift air flow. (The standard 45 degree face is best for durability.)

This thread, so far...
