Need some help with compression

Hi everyone, I would like to know what compression I would get on a set of 243 heads milled 0.30 over or 62cc chambers with the stock shortblock and stock head gaskets? I did a search but I only get numbers for LS1's I want to have around 11.5:1 or so. I'm wondering if 62cc might be too much?

On what engine? You'll need more info than that to calculate it. Bore, Stroke, Head gasket thickness, Piston dome volume, piston deck clearance?

Once you know your correct cc of the chamber, use this calc to find out .

It's for a stock LS2 shortblock with the 243 heads milled .030 and the stock gm gasket. Thanks for the replies.
