Had to walk away from it for a few days, I figured I would try starting it one more time before digging any further. So today I adjusted all the rockers again to 1/2 a turn preload instead of my first setting of 3/4 turn. Started it and this time all the lifters pumped up just fine. I put on an old set of valve covers that I cut the tops off so I could watch things for a while and its all good. I couldn't find any wrong adjustments today doing the preload adjustments a second time, and I don't think the difference of a 1/4 turn preload would make the difference why some lifters pumped up and some didn't last Sunday. Just one of those weird things, but its doing fine now. Thanks!
