These locks will not fit an OEM Ford spring retainer which are 7° - use the locks # 605-16 which are 7°.
You must use a 10° retainer for these locks
These Ford four groove Steel Super Locks™ feature a 10° lock angle and 11/32" valve stem size. They are recommended for all race applications because Super Locks™ have a wider angle (10°) that better distributes the ever increasing valve spring loads over the retainer than typical 7° locks. Precision-machined out of super-tough, fatigue-resistant metal alloy, Super Locks™ fit any COMP Cams® 10° retainer.
