Ed,
I think you're underestimating the situation. Some folks with a long history of building these engines apparently have gotten no satisfaction from Glyco and had to move on to find an alternate solution. Automobile Associates in CT is a very experienced shop & I would tend to trust their observations on this issue. We should be thankful that they are willing to share this info. when apparently Glyco is shirking responsibility, assuming installation or operator error.
Here's another thread with a little more detail on the Clevite substitute
