I'm going to replace my rocker arms and Im not sure on what to get. can i use roller rockers or should i replace with stock rockers?

 

If available, roller rockers will be good to 8000 RPM. That should get you moving. Otherwise go to Cummins and get standard replacements if you intend to stay within the limits of the engine. BTW, what's wrong with your present rockers?

 

nothing, I think you stand to gain about 30 horsepower by simply changing stock rockers to roller rockers, but i can't find them on the internet so maybe they don't make them for our trucks. Wonder if the valves would sound different with roller rockers?

 

call haisley,eep or scheid they may offer them i know thew have inconel valves, hd springs, pushrods and titanium retainers they may have done something with the rockers also
