Compression Ratio Question

[Longhorn Al]

I was wondering what kind of compression ratio I'll be looking at with my engine? I'm not sure what info y'all need, so here's a quick run-down.

It's a 383 with KB hypereutectic flat-top pistons, and a CompCams 270H. I'm planning on using the Performer RPM intake and heads along with an Edelbrock 750cfm carb. I also want aluminum roller rockers. What other info do you need?

I wanted to know this because I've been seeing guys here suggest dished pistons to get a good ratio and be able to run on pump gas. I've already bought the pistons, so it's a little late for that. Will my engine be ok on the high octane with whatever compression I'm going to have?
