basically a domed piston is the exact opposite of what you want for low compression

you'll want to look for a dished piston

also LT1 heads are around 54-56cc. so if a piston makes 12:1 with a 64cc head, in a smaller space with 54cc heads it will be a higher compression of more like 13:1

btw hopefully you're not running a meth kit and 60# injectors currently on the car

Being that you know absolutely nothing about the internal workings of an engine, I'd pass the short block off to a qualified experienced engine builder.

Just cause you have a lot of money in metal in the shortblock doesn't mean it will stay together. Find someone with some FI motor building and tuning skill.

8.5:1... probably too low. shoot for around 9.5:1. Start looking through catalogs to find a piston. I'd look at JE.
