I got the cylinder head back from the machinist. Took 6 thou off and it looks great. On one of the cylinders it looks like something tagged the side of the chamber? There's a slight dent which I'm sure won't affect anything. Maybe whatever happened to this head in its past life caused it to be out of spec and my leaking issue. I got the new valve seals in as well. Proper Yamaha ones with a steel jacket and viton rubber. Lets get this done.
