Making power out of the 318

I figure like this if I need the 360 J heads for the 318 why not get a 360 and get rid of the dished pistons and call it a day...up compression that way :)
I right now have a spare set of js and am thinking of obtaining a 360 over the 318. I figure like this yeah I can build a 318 but in the end no one would give what its worth not true for the 340s 360s...if broke guys don't already think like that that's why they are broke...:)
