These are morels I purchased cam lifters pushrods chain and springs from Webber a couple years ago and installed it in the motor I had in the car. Great guys to deal with IMO.
I have seen some of the issues guys have had with these lifters and the roller shaft. Mine still appear tight and from what I have read the new ones have a snap ring to ensure the shaft stays in place. They not loud but you can hear them mostly inside the car when rolling to a stop.
Bottom line if I did it again I would use the Morels and probably Webber again.
