ProComp/Speedmaster aluminum heads

low as .025, was never a problem. but THEY say you shouldn't. lol
I know when my engine was originally built it was.010 above deck. of course when I read the paperwork that's how much they shaved off the top of the block to get it square.. so as it was discussed with me the engine builder instead of using a fatter gasket then the 1008 at 39 he gasket matched countersunk the heads around the edges so many thousands to accommodate... He seemed to be comfortable at a minimum of .030?
So now I'm faced with this..

(" IF ") that is actually .010 above which I have not personally measured and that is a 5 year old picture when the block was being built, then a 1008 should leave me .029? And a 8553 should leave me .043?..
Edit: I would also appreciate @70aarcudas take on this post??..
