Yeah those exhaust ports were like that when I began work on those heads. I deemed the intake valve size and repaired the intake ports to be adequate. I also assessed the ultra raised exhaust ports as I knew where and whom these heads came from....figured they make mondo torque without spending 10 hrs on them. As for the header gasket port overlap???? Big deal and it ain't. 250" plus it's the floor and the exhaust ports being this way is probably why this beast had 17" manifold vacuum @ 1080-1100rpm when it left my place. I love how all of a sudden there are no headers in the world that will ever fit those heads!! Hate to tell you---those are just ordinary TTI E body G2 headers that you just ran. J.Rob
