performance rocker arms - any difference ?

[1965lonewolf]

looking to get some roller rockers for a farmall h , have some engine work done , would a set of roller rockers be good ? how much torque & power would you pick up ? thinking of a 1.95 intake and a 1.75 exhaust. Any thoughts on this ?

What kind of engine work? Did M&W make a rocker arm for IH H or M? I got a real weird looking set I found on a H a while back,,,, No part numbers. Chad

Hi Chad , Sorry to hear about your Dad. Yes M&W made high lift rockers. In the 50 -60 yrs we use to have to hone & fit to the shaft. R&R in Illinois makes a super nice True Roller(Roller on the pivot & valve end) rocker arm Earl-IL

Hi Earl! I miss him alot but were moving forward! Ill take a picture of the set I have and send to you. They are cast iron, not stamped steel, they measure differently from tip to pivot, and from the pivot to the adjuster than the stamped steel set. Did they have part numbers? Chad

I thought it was a H! LOL! Sorry. If your running a custom cam now,, you should check to see if your not going to bind the valve spring with the stock set and a custom cam. Chad
