is a head w/a 58cc combustion chamber streetable? ive seen that w/ a 58cc combustion chamber and a stock head gaskit that you will have a campression ratio of over 11.5to1 . is this to high to run on pump gas, and will it be streetable?

That's cutting it damn close for pump gas.. I wouldn't recommend it. gains aren't going to be worth it.

It is streetable. I ran 58 cc heads with a stock head gasket on my 346, and am now running 58 cc heads with stock gaskets on my 383. I have around 11.8 static CR right now, and do not have any issues. What you need to watch is your DCR.

^ Quite a few people have made calculators regarding DCR on here. If you search DCR calculator you should be able to find it.

Depends on your DCR which depends on your camshaft.

Search for the Piano Prodigy DCR calculator.
