Pete,
I wonder what type of valves and guides your engine had. I install those type seals on intakes and exh for all street engines. Race engines get just the oring on the exhaust to somewhat limit oil.

Valve seals, new style much better


Mark,
Are you using Teflon seals on the exhaust guides too?
Just wondering if you discussed that with your machinist?

I had a head done with all Teflon seals and the exhaust guides were heavily worn at the next valve job years later. I was told the Teflon seals cleaned the oil off the stem too well.
He liked them for intake valves only, and stock or umbrella seals on the exhaust side.
Just curious and others please chime in if you think the guy was wrong.
Thanks.
