I am thinking about advancing the timing +4 but don't want to if I have to run race gas. I have 155 psi compression in both cylinders at sea level. I am running 93 octane right now. Am I pushing it with pump gas at this compression or am I ok?

You are pretty close to pushing it where you are at. You may get away w/it, I am not sure I would risk it though.

I think that I heard 170 and above you need to run race gas. But I wasnt sure. I have heard a few different things?

 

I've got 152psi in each side and plus 4 timing on 91 octane...I'd say you'll probably be ok...
