Thanks. My thinking with not relying on the head gasket to increase static compression if I lose some with cutting deeper reliefs was that I'd be battling myself to a degree, in that I'm cutting reliefs deeper and losing some of that cut by bringing the valves back down closer to those reliefs with a thinner gasket. There's going to be more cc change in the head gasket change than the relief change, however, so I could find the sweet spot where the additional relief to account for the valves and thinner gasket will net me the static compression I had before the relief and gasket change.
