Hmmm. I'd be more suspicious of coil bind or bad geometry than over-revving for spring failure. My engine just rolls over at about 6k, but springs don't break. There are short travel hydraulic lifters for the FE, but I'm not sure that's the problem here. And Brent can certainly correct me, but running a typical roller juice lifter to 7k is absurd. Solid roller for sure but not hydraulic.
