Post stroker combos

When I used to run 400s alot I kept looking at the CH compared to the 440 and figured I could make a 480 fairly easy if I had a 4.125 crank. So now I have a 4.125 crank, 400 pistons on stock 440 rods and stealth heads in a +0.020 440 block. It bolts together nice but still haven't picked a cam which will determine fly cut if any.
