I’ve sold several sets of 96829B’s.......... some of which are used in cars that get a fair about of street use.
They have bushings instead of bearings, and the bearings/bushings have pressure fed oiling.

No problems reported yet.

One plus, if you’re looking to step up from the std 829’s is they both have the same pushrod seat height.
So, it’s a drop in upgrade that doesn’t require different pushrods.
