When you install the yella-terra rocker arms you starve the distributor gear & camshaft gear of very needed lubrication.
To fix that condition the second & third lifters are on either side of the oil hole above the gears.
You can cut a .025" x .025" groove in those two lifters and that will flood the area with the necessary lubrication to prevent scoring of the gears.

See my new tech article if running 1.65 yella-terra full roller rocker arms with a DUI distributor for extra distributor shaft oiling with extra gear oiling.
Hi Bill, do have a link for your new tech article for a DUI dizzy and yella terra rockers? Just want to make sure I'm reading the right thing. Cheers
