I am using https://postimages.org/I don't know if it was just fermented grape juice thirty when mbf made the set a customer sent me to install in a head or not. But I strongly urge to inspect them before installing. How is everyone uploading pics on here now that photobucket is not free?
I can't quite translate your post back to sober language. I am guessing you are saying you got some subpar valves from MBF.
I'm not recommending any of MBFs products just making lists of off the self parts. I haven't made any selections yet.
