I am just not familiar with the CMB 90 RS EVO
Squish clearance for 50%
Do I need to make a new head button to suit 50% if so what cc’s
Do you cut Zimmerman disk
What does this engine like?????

The alloy head is a home made mod
probably to add extra water cooling
A ops 65 gold head has water around the allow ring only and has a no water finned head on top of a small head button
Apart from the water cooled band this is the difference in the casing and finned top more or less...
