1) Can anyone tell me for sure if this is a stock head?
2) If I decide to remove some material for higher compression, how much is TOO MUCH before valve clearance becomes an issue?

Valve clearance won't be a problem, Stock pistons protrude about .030 out of the block. Machine the head until you have about .030 counterbore left and the thickness of the head gasket will be your clearance.
It peps it up pretty good. I have this setup on my 30 coupe.
On my 28 with aftermarket pistons that don't protrude I was able to machine it until the counterbore was completely gone, about .125.
