I just tried today to buy a set of those spacers Bob, and it seems they make them for Chevy but not Ford. I tried at two local speed shops, but am going to call Summit.

One speed shop that specializes in Mustangs came up with a theory of what happened. The screw in rocker studs we had are too short.........the polylocks were just sitting on about 4 threads of them. I bought a set of TrickFlows from him that are longer so the polylock grabs more of the stud. He felt it created a weak spot there and that is why it broke.

He also questioned our geometry, and to be honest Don and a buddy put the engine together and they didn't check that. I am going to install the new studs and run a test to see if I need longer or shorter pushrods to make it right. Any easy way to do the geometry test without using lighter valve springs and all? What kind of dye do you guys like for the tip of the valve stem? Any tips would be appreciated.

Sure glad there is FedEx and UPS overnight shipping......it may save the day for him yet. BTW, gotta go pickup my T today. The upholstery guy is done with it as far as he can go for now.
