Lightbulb Any Guesses? 58.6cc Cylinder Head Compression

Hey Everyone,

Bought my car and the guy gave me a couple LPE CNC ported cylinder heads with the car. Next to one of the combustion chambers someone wrote 58.6cc. Can anyone tell me about what compression ratio they would give me if I was to install them? Would I be able to run pump gas with these? A Big Cam? Should I just sell them and get some heads with a more reasonable chamber size?

TIA

About 11.4 on a 346 ls1 with a stock .054 gasket.
