Might be easier to send your domes to dasa and have them cut... you can email them and discuss it...

You could purchase 26cc domes for that head back in day. 23cc was standard superstock size.
what is your psi with valves open? If it’s around 195 psi your setup is standard.

domes are flat top or Kawasaki squish. Those piston crowns are Kawasaki style

I havent test with valves open a person that had this egninge a long tile ago had the same setup but he had 215psi so i think something is done with it but dont no what

Is there a base gasket or is it just silicone?

since your dealing with 85.5 and stock crank maybe yours has low port height. Normally 785 was 81 bore +8mm stroke.

The cylinder is coppar and silicon and the topp is orings
