Please keep us posted. Curious to outcome.
I am very familiar with GM stuff and build my own engines for drag car. Few weeks ago I broke a polylock on a 350 during burnout at 6500 RPM. Started running on 7 cylinders and made 3 passes with car slow. Found issue with compression tester, 60 PSI instead of 220. Intake valve not opening. Had to pull intake as lifter was shot out of bore. Put everytthing back and replaced one rocker stud and car normal again.
Broken rockers not unusual on early gen small blocks. Never seen valve train open on v10 ford. I hope everything works out well for you.
