In proven theory, a flat top piston with a smaller combustion chamber is better for engines, flame travel hot spots are eliminated that can cause detonation, domed pistons increase weight that affects rotating mass, efficient combustion.
Since you are building a everyday motor and not out to attack Twinkies, a new piston with a good bore is always peace of mind and will fit your needs. You can put a .030 head gasket with those pistons to help out but make sure your pistons have designed valve clearance.
