1.65 adjustable rocker arms

Figured I'd bump this in light of the new Power Nation Slanty thread, and that I answered My own question by going back to the site link here. Since the adjusters are cup style, they are pressure-fed & drilled to feed oil to the ball-end pushrod end a-la H-S rollers on-shaft like the Olds units, so they feed the EDM lifters down thru a typical drilled ball&ball pushrod......which given the arrangement may accommodate hydraulic lifters/cams with the appropriate oiling supply to the top...not that you'd want to particularly.
