Don't get to bent out of shape about them being 72cc. 10;1 is the magic number for street use. If it is daily driver, and pump gas only. You will be glad you have the 72cc. A decent flat top piston with 2 valve reliefs and it should get you real close to 10:1, might even put you just over. Anything more than that and you end up running octane booster or mixing your fuel; 92 with some racing fuel. I didn't want to be hassled with that stuff on a daily driver. But it all depends on what you think is a hassle haha.
