Another satisfied customer

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!

Proposition 65 Information

"Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm." -  

So, what does this mean for Goodson customers? It means that many of common products used in manufacturing contain products known to the state of California to cause cancer and/or reproductive harm. Components such as stainless steel, galvanized wire, brass, bronze, etc. can be found in the Prop 65 list and require us to provide the warning. 

You can find a complete list at the Proposition 65 website.
