They are in a super m block

Comformatic Pistons sold by Tractor Supply in the 70s look exactly like that.

Can I run this 450 lap head or do I need to mill Pistons down or change them?

Having asked this question because I am planning on doing the same thing you are I have been told that they should not hit the LP head. While you have it apart, if you have a Super M cam then you will gain a lot buy going to a cam reground for pulling.
