+1 on Harland Sharp. Currently rebuilding my 540 n/a. The Harlands are going back in. Was going to replace them, but couldn’t find any wear or bearings that weren’t smooth.

According to everything I have heard, Comps1820-16 (Ultra Pro Magnum XD) are about the best you can get. I am not a fan of the Scorpion products.

Just to close the loop on this encase it helps someone else... I ended up going to with T&D shaft rockers.

Well, that is fitting. Lol

Baller - extremely good or impressive; excellent.

now you need some clear valve covers so you dont have to cover up the jewelery.
