So I go to start cutting some valve guides on a set of stock iron heads to fit .530 viton seals. I have the .530 guide cutter from Comp Cams that I bought from Jegs. I get one guide cut down to height and go to put on a seal. It is loose as could be!! Wth? I start measuring everything and it turns out the ID of the cutter is .5255. The ID of the seal is the same size and therefore has no pressfit. I am guessing I have a defective cutter? Shouldn't the cutter have an ID of .530 and the seal have a ID of .525 for a .005 pressfit? What am I missing?
