I have a 2M crank in a 302, pistons are flat top with large D cup (Speed Pro forged aluminium, printed "LT-16" on top of piston) to accept 2.02 valves, Heads are 60cc chambers aluminium. I took a wild guess at 9.5/1

Can somoene tell me what my compression ration is or what other infos do I need to give you ?
If I wanted to increase it, what is the easiest way about it ?

Here's a site that has a good compression ratio calculator on it. You need a lot of information to get the exact compression ratio.
