I found an article on Yellow Bullet - Post #6 at http://www.yellowbullet.com/forum/sh...d.php?t=537267 that may be helpful. He also mention's the exhaust angle is 18* - on the 18* Big Chief's.
It's - that post - a good reminder, that all exhaust ports must be checked with anyone's headersmanifolds that the port / header opening's match. I've run into these issues with standard stuff. 23* SBC even.
This is the way I've used to check both. Works pretty slick and a little more accurate than using a gasket to check.
