Uhhhh...

1) Are you setting up your rocker GEO at HALF LIFT...???????
(I don't see that in these last pics)

2) AND are you using an adjustable pushrod to check GEO?????

3) If so (see #2) Is the adjustable pushrod have the same tip as the the other 8 full length pushrods that you will be installing in your engine?

4) Have you read Jakes article on Rocker GEO at his web site? It's a long read. And it might help you figure this out.

The second set of pics were taken with the rocker sitting at 1/2 lift.

I am using the adjustable p/r to check geo

The p/r does have the same tip I will be using

I have read (and re read, and re read (IMG:style_emoticons/default/biggrin.gif) ) Jakes article.

I had to make a new adjustable p/r. It's quite a bit better than the one I was using. I went through the whole process again with the new p/r, without the rocker block shims.

Once that was complete, I was not satisfied with the 1/2 lift results so I added the shims and left the p/r locked at the same measurment.

I then added the shims installed the p/r, adjusted the swivel foot to make contact with the valve and cycled the engine.

The total lift was ok but the half lift geo was still off. I then made the corrections to the p/r and swivel foot.

after the corrections the FULL lift was good(i lost about .002 total lift but well within the 5% range) and the 1/2 lift geo was quite a bit better.

These are the second set of pics, after all the corrections, with he .030 shims and at half lift.

My p/r measures 251mm end to end w/o the tips, so 271 total length
