[A bones]

I guess it was when i was young and dumb I, took my head to the local parts jobber with a machine shop. I spoke with the machinist to say I wanted it cut. He looked it over and turned to his assistant and said, "You can really cut a lot off of these with no problem".

Upon my return I was informed that he noticed a lot of rust flakes which he hosed out with water and air. If told me how much he removed, my brain was busy processing the cooling issues.

Bottom line it performed much better. Hills became less of a problem.
