In an earlier posting someone wrote about grafting in a larger valve block (block, casing, and pistons) with a bigger bore. Can this be done without causing problems, perhaps of the difference in size of the tubing and the ports in the valves? Is there a definite advantage in the sound with the larger bore valves or would all the tubing have to be larger? Thanks, Bill
