Good question! I knew someone would notice that!
If you notice, my crap heads have the smog hole in the side of each port. Well, I couldn't grind all the way to the edge of the paint as it would chew into the edge of the hole. I decided to cut it short and leave enough material so the gasket would seal. On my puny exhaust valves, the extra 1/8th or so won't really matter.
And yes, the headers will be gasket matched. I'm going to leave the header slightly larger than the exhaust port on the head so there will be no restriction...
