I have an Atlas head, just built, and I notice the left exhaust rocker strikes the valve off center. It is possible that the valve guide hole was bored off center but I would like to compensate and get it to hit right in the middle. I ground a bit off the rocker so it would sit a bit more outboard and shimmed to suit. All is well until I tried to install the head and found the pushrod was not going to engage. Apparently the pushrod has very little room for variation. So I chucked the rocker and installed one of my spares. While doing so I noticed the rather clumsy drilling of the rockers for the adjuster. It looks like it was either drilled with a bias towards inboard or the casting has extra metal on the outboard side. What I am wishing for is that if I had 10 rockers sitting on the bench, no two would be drilled in exactly the same position...sort of like finding identical snowflakes. At this point I would find one that was biased towards the outboard side and my problem would be solved. Am I dreaming?
