Something else to think about.
1. Where the pedestals the correct ones ? where they the correct hieght ?
2. Where the heads milled the proper hieght by CHI ?
All this would have contributed to the incorrect geometry not just a push rod too long.
The rest of the surge and bounce theory with the wrong retainers caused the overheating on the shaft and rocker arm potentially combined with the bolt caught on the last thread ... too bad we didnt still have a broken rocker for it to be tested for stress cracks and see if over heating was the cause ? hint hint.
