Valve lash? that should be stock in all cases, unless you have some different camshafts that require a different adjustment.

so whats up with that chatter.........is louder than usual......the timing is on right and all?????????? ???

I have no idea... chatter could be a bunch of things, I cant hear it, so I cant tell you what is wrong. You probably didnt adjust them right, it just takes one of them to make all that noise.
