Well, with the 205cc port being 1.342 x 1.375 the 1.650 O.D. "402" headers I have should be more than big enough to eliminate any restriction. As I mentioned...they expand to 1.75 about 6 inches from the flange and remain that size all the way to the collector.

I always matched gaskets and cleaned up welds on the flange in the past, but with the clearance I think I will just leave them alone. In the beginning of this thread I was afraid even the "402's" were to small, but I am relieved I won't have to spring for new headers.

I'm glad to see the port size numbers...thanks, Greg. I'll have the new 3 inch mufflers in 3 weeks. tom
