use the compression checker in the tool box.
you give it you bore stroke head CC and gasket thickness. http://www.thedirtforum.com/Cidcalc.htm

I check according to the calculator and it appears to be about 12.2:1 with out the dome included. What would be amount of a .100 dome piston?

I thought the .100 were 11-1 with 64cc heads. I would say it would be 12-1 or dang close.
