Comp valve keepers- Is this an issue??

Ok, I think I get you. The retainers have to match the locks, as far as degrees go? Your new retainers 744-16 are for 7* locks, which you have(606-16). So new stuff is good for new valves. Im re=reading my thread I linked above as we had the EXACT same issue. In my thread link the pics dont show up immediately but if you click on them they show up pita lol. Lemme do some reading.
