Well, I got the hold downs "adjusted" by way of a belt sander, it took a while but turned out pretty good for my first time doing this. I got the pushrods installed and it looks like I sized them just about perfect. With .025" of preload (which BTW is exactly 1/2 turn on the Comp SS Magnums) I have one (1) thread showing below the rocker arm bottom. The motor should be ready to install the first part of next week and fire up a few days after that!
