Well something new....now you can get these cam followers with rollers that no longer have the needle bearings and instead have a bush. Which means should you find some excessive play when doing a valve lash (issue) you can actually pull the manifold and follower, replace the bush in the existing follower and happy days!!!

Best thing since sliced bread. They will be going in my engine for sure!

i saw a set of these bushers the other day and thought what a killer idea when the time comes for a cam change on my l98 it's something i def will be adding . i believe some engine machine shops have been turning these up as well in there own little engine building tricks ..
