Who has any experience with the ferrea valve springs and retainers??I know they are supposed to be a good brand and all,but i wanna hear first hand experiences from any fellow members.Reason being is i may pick up a slighly used set from a friend.Thanks

 

i've got them in my setup, and have had no problems what so ever even reving over 8600rpm

 

they work great and I use the Ferrea stuff in almost every head I do, don't use the retainers with the stock keepers- they pull through you have to get there keepers.
