Default Whats your compression ratio?

Just interested in what compression ratios some of you are running in your engine. I have been calling a few places, looking for pistons, and was told by someone that 9.5:1 is about MAX for a street engine- which just happened to be the only thing he had available for my particular application.

So, what compression ratio are you running, and what is your opinion on the highest compression ratio for a street engine with todays fuel?

*edit* FWIW- I plan on going with the Edelbrock aluminum heads (72cc)
