Lets discuss another engine build

Hola, guys and gals.

Well I finally have the engine out of my car and taken apart. Im going to be bringing it to a machine shop to have some issues taken care. I want to go in to them with some idea of what Im wanting and would like to discuss that with you all.

What Im looking for is a street-able pump gas (93 Octane here) engine, with around 9.5SCR.

I will be running magnum heads, XE268H Cam, TTI's, Air Gap and a QFT 750 Carb. I did CC the heads and they average out to 64CC. Not sure if that is the correct way to gauge it, if not I do have the individual numbers.

After doing some research on pistons and with out getting some custom made, Im stuck between 2 different ones. The Keith Black KB362's and the Speed Pro H405CP30.

The KB362's have a 19.4CC volume, and sit at zero deck. The H405CP have a 10CC volume and sit at .043 deck. Either one of these pistons gives me a 9.1SCR.

Now here is one of my questions. If I go with the Speed Pros is it possible to shave the deck down lower than the .043 to bump the compression closer to 9.5 or will that cause to many issue with sealing the intake?

Another question I have is would there be any noticeable difference between 9.5 and 9.1?
