You nailed it, 10k miles and it was getting close to a major failure. Lifter going bad and springs getting weak.
The shop who rebuilt the heads highly suggested testing the springs every 25 hours. He also swore by PAC and was hesitant to even install the BTR. I'm sure every engine builder has their preferences.
I'm thinking at 25 hours, probably a dozen track days or so and about yearly I'll take them out and test them, maybe just replace them.
