I've built many engines over the years, and when I build one where I am unsure of the clearance due to a piston or cam change, I check the clearance using modeling clay.
I put a layer of clay on top of the piston, spray some PAM on the combustion chamber & install the head & cam, adjust the valve clearance to zero lash. Then I slowly rotate the crankshaft at least 2 times, then pull the head back off & measure the thickness of the clay where the valves compressed it. This will give you the exact clearance you have between the piston & valve & may save you $$$$.
Your total clearance will be the amount you measured plus your valve lash. If you do not have enough clearance, any good machine shop can cut valve reliefs deeper in your piston.
I have a 2.3L ford engine with the head shaved .110 & the block has been milled for zero deck height on the pistons. It also has an adjustable cam timing 'gear' so I can retard or advance the cam timing. When it was built, I checked clearance at full advance & retard so I wouldn't have to worry about any adjustments made at the track causing a problem. This is an engine that turns 8 grand on the track & cost several thousand $$$ to build so I don't take chances on something I can check giving me a problem. I've seen what happens when someone didn't bother to check & it ain't pretty. :'(
