Hydraulic Roller Lifters

I don't have "direct" experience, but I have a friend who is a rustang guy and he SWEARS by those chinkese lifters. They are all he runs and he has never had a problem with them. Even the local machine shop we both use is impressed with them. Although I do not have the link bar type, I have that brand in the little 302 Ford roller motor I just built. They look real nice to me.
