Makes a lot more sense, Piston to valve clearance has more to do with valve timing than Max lift. Generally it will be closest around 15° either side of TDC. Some cam cards will give you lift at TDC wich can help give you a rough idea without measuring.
Here is a pic from my 318 - pistons 0.014" proud of the deck, felpro 8553 head gasket , SFT cam 230°@0.050", .575" Max lift. Final assembly was done with a thicker 0.051" head hasket so I actually have a little more clearance than shown here:
