One question keeps going over in my mind. If Paul has done a number of these engine builds and all have been done using the same combination of parts with no problems what was different that would cause this problem? The Valley pan was a simple mistake that could be made by anyone of us. But here is the big question. If all the same parts were used that were used on an all these other successful builds. Then it can only be one of two things, a component failure or error made during the build. The hard part now is finding out which it is.

I dont think the rockers were a problem, but they were replaced. I would think the pushrods would be examined as well, I mean...... you are right there. I was just looking at the tops of the poly locks and noticed different heights, they should be pretty uniform. So its either a lot of bad/bent pushrods or the valve adjustment is way off, or there are lifter issues. Look at #2 intake and exh rocker set screws, they are way different ! #4 int, #6 exh, #8 int all set screws are down low, like they are set loose? I just hate the motor to be pulled and shipped for it to it end up something simple!
