S&S Cycle Forged Roller Rocker Arms
S&S Cycle Forged Roller Rocker Arms
I'm nearing the end of compiling all of the parts for my FM 128 w/FM Level A Heads and wondering if the S&S Cycle Forged Roller Rocker Arms would be overkill. I am currently running the S&S 475 cam an intend on keeping it. I already have the S&S Rocker Arm Shaft Set,
S&S Heavy Duty Rocker Arm Stud Set and S&S Head Bolts. So I figured if I'm going that far then I mine as well do the Rocker Arms, but if the consensus is that it's "overkill then I'm fine with saving $500.

I sent my Level A heads off and the guy that has been doing heads for 30+ years could not believe that they charged me that much for very little work, to top it off, valve job had a mechanical pencil lead size seat. Valve job was also pushed out close the edge. FM had nothing to say. Do yourself a favor, stay away from the FM heads.
Sounds like your 30+ year boy is trying to make a sale.

S&s roller rockers
I was told not to use roller rockers by fm. They said that they change the way the cam works. After further research ..they were right. The arms are a bit longer thus changing the lift to increase it by .019 i believe. I.e. a .470 lift would be a .489 lift. At least this is how I understood it from Chris Waddell-cycle solutions Ft. Meyers FL. You can see his vid on the YouTube. Jmtc.
