What do you mean "crouding" (sorry I´m German)
@AB I go and check the piston distance when I have the crank back from the machine shop. But I think it`s about 0.40. The deck was milled just enough to make everything square.
The 0.40 is just a guess. Maybe somebody here knows the standard distance.

Larry and I must think alike, we ask the same questions.
Frank, don’t go by standard piston to head clearance, when you get the crank installed; install a piston rod assembly and measure to be sure.
What is the head gasket thickness, are other thickness available?
With over ½” head deck thickness you have options. Any reason why you wouldn’t consider milling the head to raise the compression to 9 or 9.5:1?
I like your proposed groove location, how are you planning to cut the initial groove?
