Does it look like the rocker arms were getting oil at their base? The rocker arm shaft (if you remove it) needs to be kept in the exact configuration it is in. In order and left & right the same. It won't hurt to clean it & every other tube you see on there. I've heard of folks using a wire in a drill for the tubes, but I never tried it.
Where are you at in South TX? Somebody might be close enough to give you a hand checking this thing out.
