I think that if you want to CNC your own combustion chamber, you should start with an Iffy head, as they were thicker back a few years ago. Not sure about noe. as for boring a head for the piston clearance I made a cutter from a file and ground it in a lathe with a fixture set at the radius I wanted and hand sharpened it by hand. I poste some pics of that about 10 years ago.
