Quote: Update on motor, saturday at work we took the other head apart and no broken springs on it either. All locks, retainers, etc are Good yet. Tested all the springs at 1.900 install height and they all tested 130 to 135 closed and 235 to 240 open. So I don't believe there was a spring issue that caused this.
shouldn't those be more like 335-340 lbs.??? 240 lbs open would be fine for a stock chevy 283 though.
