Just wanted to comment on these reamers. I’ve been in business for close to 50 years. I, along with other shops I work with, have fought the good fight on getting bronze guides sized properly, with so-so results. This past Summer, I purchased a full set of the 11/32” range carbide reamers. These are the real deal. One pass, using the Goodson fluid, and you are done! I would not have believed it unless I did it myself. Great product, they need to be in every cylinder head shop!
