In my head this seams like a plausible valve to use in order to attain the proper radial valve clearance... they measure 2.16 1.59.. These should be fine using the sand paper method to flycut correct?

I'm curious, have you cut a 2.04" diameter relief for a 2" valve and seen the piston after it was run?

Yes. that is exactly what I've done before. I did it el cheepo way using 2.04 valve and stick on sand paper. After initial cuts, you do once over with finer grid to deburr and remove any edges that can constitute a hot spot.
See on a 346 piston, bigger than a 2.05 like (2.08) will work as well but the edge of the eyebrow on intake gets very close to ringland which weakens it. So for this reason, IMO 2.05 is best but 2.04 will work as well perfectly.
