Oh, wait a minute. Didn't they use to do that? Wonder why they changed? Hmmmmm

Isn't the class you are running called "Stock". So if manufacture "F" used a better valve spring than manufacture "G". That might have bin a reason to maybe run manufacture "F" engine. At some point it seems people who run manufacture "G" felt entitled to be able to run manufacture "F" type springs. Before you ask, no I don't run a car in stock and have not for over 45 years.
