Yes, I'll check my notes when I'm downstairs in a while. Pressure gauge is so unreliable when you get up in comp on a small engine that I won't use them. Should ideally get to say 0.9mm. But you will 100% have to cut some material out of the chamber to get ratio to a usable number. I measure on the bike, far more accurate. Can't flatplate due to stepped design anyway.
Do a search to my thread on doing my 300 head and read up. Helped my 200 a lot too.
