Can I make this work on pump gas?

This piston is domed with valve relief so I checked the flat part to make sure it was zero deck, then dropped it .5 in the hole to be able to cc the dome.

I am more than willing to change the cam and/or head gasket to make this work. I just need to know what I should change it to.

I have a 318 in the car now but would like to know if I can run This one and get some more performance.
