Pistons needed KB 107??

I will soon be starting on a build of a 360 for my '74 Scamp. I picked up a block off of Craig's List with a standard bore and I am looking for some pistons that will give me a liTtle more compression. I was thinking KB 107's. Does anyone have something I could use? Since the block is standard bore, 20 or. 30 over would do the trick. Let me know. Thanks
