Who can cut the runners down on a 502 mpi

Anyone with a mill. I can do it, but I'm sure you could find a mahine shop near you to do it. It is very easy. You should also open up the top opening of the runners. You want to basically lay back the opening of the runners on a 45*. You also want to cut down the center divider at least an inch. This will in effect shorten the runners. Let me know if I can help.
