If you have canted heads with 120+ gram valves and crooked pushrods you are going to need valve springs....you inline valve guys with tiny valves and straight pushrod geometry should never break a dam thing.

Its as simple as that

1 spring rule for everybody is not a cure all.... guys that race,.not bracket race the combo will always push the limit

watch how much "breakage" Prostock is going to have with a 10,500 rpm limit...should have left that alone also
