Default Re: Overbore and intake valve size

In addition to more cubic inches, it will unshroud the valves and chamber which it is a plus for engine flow.

Thinking out loud....the extra weight of the piston is of any concern? The cylinder fills to capacity regardless of any restrictions(valve size, head design)?

The piston has a spec weight, regardless of over- bore size.
Everything helps on a small motor, but make sure you concentrate on minimizing the deck height.
