rocker chatter

[Billy8380]

Stock ported e7 heads oversized valves, tfs stage 1 cam, stock pushrods, stock rockers and they will not tighten down and chatter like crazy

What do you mean they won't tighten down? When you set the lash you never were able to get them close to the torque setting? I know I had to use shims on mine, but that was when I went to rollers..

The TFS Stage 1 cam is probably ground on a smaller base circle than the stock cam, which means that you're gonna need longer pushrods to get the correct lifter preload. Buy a pushrod checker so you can find out which length pushrods you'll need.

yeah that is what I thought, I had a set of 1.6 rollers that tightened down with no movement but wouldn't clear my valve covers so I sold them and tried to go back stock but ran into this problem, now I have found a set of ford motorsport 1.6rr has anyone ran these with stock valve covers.
