i'm running 1.80/1.50 valves with .030 over bore and have no clearance issues

But your valves are REALLY shrouded. You MAY get lucky but why take the chance. Did you bore notch? Have you had the head off? If so I would love a picture of the head and bore just for my own records.
Ill say your machinist is good getting 1.80/1.50 to work.

yes i have had the head off 3 times and its off right now. the head is notched where the 1.80 is but not the block. Not sure who did the head i bought it done, it was someones spare head for a circle track car from the 80s.
