Ferrea valves are the only valves made in the usa, Even Manley are now made over seas they sold the company. Are the valves you ordered stainless?

All of the valves Steve gets for viper heads are from manley. All the faces have to be touched. All their valves the face is usually cut at different angles from 40 to 47 degrees. So where ever you get them they needed to be checked. Quality isn't what it use to be thanks to getting less qualified employees from all over the world due to labor rates.
