Economical replacement rocker arm set?
Also, you should drill the 2nd hole in the shaft behind each rocker if it is not there. This helps feed the hole in the adjuster side of the rocker, which then dribbles oil down past the adjuster and into the pushrod cup. For high revs, it is a must IMHO.
That 2nd hole is about 80 degrees around the circumference, up from the bottom oil hole in the groove, and to the adjuster side side of the rocker (which would be the uphill side of the shaft). It is .125" diameter. You can see it here; the shaft is upside-down in this pix.
