Rebore the stock VBB2 cylinder for an OS deflector piston or replace cylinder, head, and piston with new domed version ?

The deflector Piston is of historical interest only.
The transfer ports are a completely different angle in the barrels and domed pistons have many advantages over their ancestors.
