These appear to have bronze bushings, much like the FPP assemblies I used on my iron 427. I preferred these over the Dove/CC rockers when I purchased them 15 years ago since they are bushed, instead of running the 'bare' aluminum against the shafts. They are a little bit different, using a ball/ball push rod. I did swap out the FPP end stands for the Dove end stands that tied into the end head stud. They held together fine, I was running a .645 CC roller and ran up to 6500rpm. I will reuse these when I rebuild the iron 427. I am not sure what kind of price is on the complete assemblies, but adding up the individual prices on his Ebay store is a little bit more than the Ersons. He seems to have a pretty good reputation. For my aluminum 427, I am using the Ersons.
