I'm getting ready to put rocker arms on my heads. I have '66 289 heads, and I'm putting on 1.6 3.8 stud roller rockers. Do I have to adjust them with the feeler gage or tighten them all the way up or what? Would appriciate any advice on this. Tony

Do you have a solid or hydraulic cam?

do your lifters have little wire spring looking things on the top end of them. sounds like you got a roller cam motor by the year model. MAKE SURE that you have a steel or bronze dist. gear. the cam will eat up a cast one.

That's a hydraulic roller cam. You'll need to preset them by running the nut down while spinning the pushrod between your thumb and finger. When it's tight enough to stop the pushrod, turn it 1/4 turn more.

Then you'll need to adjust them while running for the best results, using rocker arm clips to prevent an oil flood.

You'll need the pushrods for the roller cam, they are shorter than standard 289 pushrods.

YOu have to adjust them for some pre-load into the lifter.You must set them one at a time with the lifter on the heel of the cam.
