11 to 1 on pump gas

Well I will be installing the motor in the next week or so. I had a operation on my ankle and I'm off my feet right now. I was thinking about going with a thicker head gasket but the guy I bought the motor from said I would lose the quench. I don't mind blending a little. I talked to a engine builder here in Houston and he says if the motor has really good quench that would be at the limit with 93 octane. I'm not stuck with these heads I thought it would be cool to expirment for 3 or 4 months and see what they can do. I am worried about he summer though 100* with 85% humidity might be stetching it. There seems to be some pretty sharp guys on here so keep your eyes open I'm going to need help
