400 stroker rookie

With the rockers removed lay the edge of a steel ruler (or similar) along the tops of the valve stems. Even if they're slightly different heights you'll be able to see if the tips are parallel to the straight edge. The same applies if you put the ruler in/along the bottom of rocker shaft recess in the head. If both checks look 'level' then the rocker arm pivot may be bored pissed.

I've used to different straight edges and wish my eyes was better. I took everything off the rocker shafts and tried with 3 different rockers ( sliding back and forth a Little) and seen most of them fever 1 side. I checked the rocker stands and did come up with end to end difference. Think famous Bob has seen this before
