I ordered Supertech valves but they seem to be on backorder and I'm kinda in a hurry to get some valves so the machinist can begin to work on my GS-R head. Has anyone had any experience with RM valves? Looking to get both good and bad experiences. I already have the RM springs and am waiting for the RM retainers. Do the RM valves have many of the same properties as the Supertechs or Ferrara's?

Good parts.

 

I've researched alot on there springs and retainers and have heard nothing but good things. I just haven't heard much of anything about the valves.

 

No one uses or has used RM valves.
