If you got it "right" on the first try, I submit to you that you probably have too much tension on the bars. The reason being, there are "jounce bumpers" that the IFS 4x4 Chevys ride on at unloaded ride height. It is impossible to push the front end below unloaded ride height. So you may think you're right on, but you're really way over.
According to his numbers, he is not trying to push the front axle below the stock unloaded ride height. He is .25in above the stock height when the WD bars are tensioned.
This is probably just about right but I would try to get the bars parallel with the A frame so that they ride flat on the L brackets. I think I would lower them one hole and tilt the hitch head back by adding at least one more washer. For the standard sized A frame, Equal-i-zer recommends starting out with 5 washers in the hitch head and he only has 4. When he lowers the L brackets to make the bars level then he needs to tilt the head back some more to keep the same tension on the bars.
What he describes sounds like he could use a bit more tension on the WD bars so I would add two washers and try it out. Can always take one out if it puts too much tension on the bars. The porpoising he describes is a typical result of not enough bar tension.
