Valve Seat Cutters

I've got a Sioux valve grinder machine as well as the valve seat stones, guides, driver and various attachements. I need to get some larger stones to do 2.02 intakes. Just for fooling around on my junk and maybe occasionally for a friend. Would this set of steel cutters be a good accompaniment for that if the diameters and angles are what I'd need? I assume these would rough the seat in and then would either finish with a stone and/or lap the valve? I've never done this before but I got a good deal on the setup and I like tools. I've seen new import sets on ebay that look like they have brazed carbide teeth. Price is more than double for the ebay stuff but I don't want to buy something that isn't useful.
