Well I ordered myself some new valve seat cutters

While spending a couple of days with my buddy flowing his heads he was telling me about some custom seat cutters he had. I have been using Neway cutters for the last five years or so and have been limited to 60-45-30 and 15 degree angles. Some of these heads really look like they needed a 70 degree bottom cut so I ordered a couple different 70 degree sizes, a 30, and a nice 15 for top angles. With the guides and needed tooling it came to slightly over 200.00 and a 3-4 week period to make up the kit. Can’t wait to try them out.

What brand are they PBR? I have been close to pulling the trigger on either an old Sioux stone grinder or a set of Neway cutters a couple of times but neither option is inexpensive. Care to share a link and what number cutters we need to handle valve seats in common small block and big block sizes?
