My 440 rebuild thread

Well, ****. This is embarrassing. I had Pops over today to help look over the engine, and one thing I hadn't done after seeing the rockers all the same angle, was turn it over and watch to see how they moved. We did that, and they all move just fine.

So I'm back to square one, with an additional question. How did the rockers end up the same height? Was it from the lifters bleeding down? I think the cam might be fine, and with #6 and 7 plugs being carbon fouled, maybe an ignition issue.
