Help with Set up and Pistons for 370?

Ok, so after some debating in regards to what combo to run 376(with ls3 top end) or 370(with cathedral heads) for my lq9 block. I have decided to go with boring the block .030 over for a 370 and going with Prc 2.5 5.3 heads and either an ms3 cam or tsp 233/239 cam with a goal of 450-470 rwhp n/a. My question is what type and style of piston can I use to keep my Compression any where btw 10.8 or 11.2, as I would still like to run 92-93 octane?

Why aren't you using ls3 heads on the 370?

With my 370 build, I'm using wiseco flat tops with ls3 heads, and a custom cam. You can use 93 octane and still run 11.5 to 12 compression. It's all in the tune?

I really would like to keep my compression close to stock.
