Only way you're going to make that head work on that block on pump gas is to install new Pistons with a dish. Which means,basically, a complete rebuild. Or you could run 100 octane race gas at $5-$8 per gal. (Depending on where you live). You don't have to take my word for it though. Put it together how you want and see what kind of knock, ping, pre-ignition you get. Maybe you'll be the lucky one.
