Which Rockers are Best???

I would take the banana grooved shafts and put the bushed rockers on them and sell them to me. Just fooling use the above and sell the rest. Use the solid spacers if they line up good with your valves.

I appreciate the humor...I was wondering if I could mix and match?? You mentioned bushed rockers, do you mean the bronze ones that have been ground for bigger valves? I hadn't checked to see if they were bushed?? On closer inspection it almost looks like someone may have plugged the hole that was on top of the bronze rockers and drilled a hole under the arm where it was ground for clearance??? I was hoping someone who has seen this type of set up before could shed some light on these rockers.
Also wondering if one type of locking adjusting screw is better??
Has anyone else seen this type of set-up??
Thanks "Mod5v",
