Reworking the 273 Adjustable Rockers

Jad, VG info! To clarify: (1) you are drilling a hole in the rocker (& the shaft) inline with the underside of the rocker arm/valve interface? (the drillbit photo?) and (2) you are drilling the OE hole in the rocker on the threaded adjuster side further inline into the shaft at the right clocking (with valve closed) then closing the outside hole used to access it (same one Ma used to originally drill it) but Ma did not drill thru to the shaft at that clocking and that is what we are adding?. Correct or not correct? thank you for your time bro. RR
