I think your pipes are probably the same as the ones I got from Mike's. I assume they have the stepped ends that fit into the step in the port. They will seal very well. The issue with my MAC pipes is they weren't made like that. All they had was a very small rolled edge that was supposed to stay on the seal ring and seal. They didn't, easily slipping off the ring as you tightened the flange down. I "fixed" them by adding the stepped ends of stock headpipes. This centered and held them on the seal rings, and sealed them into the head very well .....
