Turning the valves with them fully closed mean either you don't have proper valve clearance, or there is something wrong with the valve seat to valve interaction.

30 psi compression is TOO low after pulling the head, and replace the head gasket and look the cylinder walls, if you can see visible scratches or a ridge in the cylinder wall then you will have to get it honed
also check for burned,pitted or sticking valves, you have to turn it over by hand to check that
if the headgasket doesnt help if the cylinder walls and valves are in good condition, then you should look into a new set of piston rings, i would go with a new set of rings if you got the engine that far down already
