Adjusting Rocker Arms

[420nitro]

Wow ...I never had mine that tight.

The way I do them is as soon as the push-rod is hard to turn.... I lock the poly lock.

The time you adjust them is also very critical too!

I use the following method.....
As soon as the intake reaches full lift...I set the exhaust.
As soon as the exhaust starts to open I do the intake.

That's the way I do it and yet to have any problems or issues. I also check to make sure the lifters are in good shape as well as the proper valve train geometry.

86gt have you checked to make sure you have the proper push-rod length?
