BTW, the 2 holes in the rockers don't line up with the 2 holes in the shaft.
- There is a bottom hole in the shaft with the banana groove; there is no matching hole in the rocker there.
- There is a small top hole in the rocker but no matching hole under it in the shaft; this top hole just dribbles a little oil out that eventually finds it's way onto the valve stem tips.
- The only place where there are holes in the shaft and rockers that come close to lining up is on the uphill (pushrod) side of the shaft where the matching hole to the adjuster resides. This is where the matching of the holes may be useful. (I am of the opinion that if these 2 holes pass each other at sometime during the valve lift cycle, that will be adequate for most typical uses; spring pressures at or under 300-400 lbs and maybe RPM at or below 7k.)
