I found the right size sealing rings that go on the 5 and 6 and the 1and 2 exhaust manifold pieces. After I measured them out and called a couple of places one guy was able to get me what I needed. They wind up being 2 3/8 x 5/32. The guy I got them from was Otto gas engine picked up his last one but he can get more or grind larger ones down. Got three delivered for 18 bucks. Thanks guys
