after quickly cleaning up the head, I refaced the valves and cut new valves seats.
Once the valves were refaced, I back cut the valves with a 30 degree angle above the contact area to remove the lip and allow better flow.
100% seal on the vacuum test.
I finished the head off with a quick resurface to get a great seal with the head gasket.
I am considering cleaning up the combustion chamber and ports a wee bit, but for now, it's onwards to the bottom end...
