So, I took the cylinder head to an engine builder in town...The owner is a bit crazy, but still a sharp machinist. He spent a while looking it over and checking for warpage across the deck...I started getting nervous, then after a very, very long conversation about RA finish levels, and gasket composition, he declared it was just fine, and in no need of being machined! Didn't want to charge me for his time, said come back if I ever needed anything down the road. Super stoked on all this.
Not stoked on still having to wait another week for my stupid backordered valve stem seals...ha
