FWIW, my fresh 383 stroker suffered a broken valve spring - the Beehive variety so no damper to hold the valve up. It resulted in a complete rebuild AGAIN and expensive work to repair my head.
Granted, my spring broke not because I was too hard on her, but because some of the springs were out of spec and suffered a coil bind situation despite the lift they should have been capable of supporting.
