302 casting potential?

So here's the deal, we got a free old ram 4x4, had a spare motor in the bed, it's an 87 318, my brother and I pull the valve cover to see if it had 302 heads and yea it does, he'd like to use them on his 318 build but isn't all that thrilled with the 1.78/1.50 valves so he'd like to know if these heads can be punched out to 2.02/ 1.60 and he'd still have closed chambers to keep compression up. Anyone know if this will work? and if he ports them, are they still swirl port heads?
