Looks like someone opened up those ports. Oh wait, I'll bet they are the 200cc version. There are D-port gaskets available, so you should google them or check Summit.

The keys to gasket selection are not to block the head port and to make sure you have at least 1/4" of seal around the header flange and the head's gasket surface. Otherwise you get blow-outs which give headers a bad rap. Exhaust flow is at max volume at the top of the port, so that's the most critical place not to block.

Enough said. I'll stop hijacking your thread.
