[QUOTE="ClassicBiker, post: 119038, member: 1632"] Dave, Russ, Funny enough the pilot that came with my Neway cutter did not fit the Shadow's lower valve guide. The taper widens out just that bit to much before the cutter made contact. The reason I believe is the sealed valve guides extend further into the port than the standard guides. Because the sealed valve guides do not extend upward from where they are seated in the head, they are lengthened to maintain support. Anyway, I was going to order a length of drill rod to do the job. When I struck upon the idea of using a 3/8" transfer punch. I rolled the punch on my granite to make sure it wasn't bent. It measured 0.373" so I went with that. I also purchased the Neway cutting fluid, which I think helped as well. I was curious as to how many rotations it would take to clean up the seats so I marked them with a sharpie marker prior to cutting.
