Reworking the 273 Adjustable Rockers

1 Do NOT restrict the oil going to the head.
2 if your shafts already have the 2 holes per rocker why do you want to plug them an drill more. You have plugged the leak on the rocker so oil is going to the pushrod now that was being lost. You plugged the hole on top and drilled the new oiling hole for the valve and rocker tip your good to go on the rocker arms.
3 .100 to .125 is a 25 percent increase in diameter isn't that a 100 percent increase in volume correct me someone if I'm wrong.
4 See answer 2
5 I don't think you want to do this. A solid lifter cam has different ramp speed an profile than a hydraulic one. Did you replace the wire clips with C clips? All it takes is a loose adjuster an a wire clip will leave the building.
6 1 thread is about perfect I thought maybe I'm wrong
7 Buy the new pushrods go with the solids

Jad PS hope your not using a stock oil pump pickup for the HV pump especially with the Guitar Jones mods.

Jad, thanks for hanging with me on this. (1) I have full time oiling to the heads & I drilled the setscrews to .080". If you want more or less than that let me know & I will drill em out further or get new setscrews & drill em smaller (2) I was thinking that you and Yellow Rose wanted me to plug the offset hole(s) with lead shot & drill a new one(s) in line with the valve tip (the drill bit pic) with the valve closed, correct/clarify me on that. (3) I had rockers that already had the top brazed shut and the hole under the arm on the valve tip side (drill bit pic) drilled to .100". You wanted 1/8 so I am going to open em up a hair to that per your direction. (5) I am not useing a hyd lifter on a solid cam (the ramp issue I understand), I am using a hyd lifter locked solid into a solid lifter on a solid cam & now that you mention that I will replace the wimpy retainer rings with good clips. (6) good to hear that (1) thread is good. (7) I feel lucky! Holler back when you can. EDIT yes hi vol pump/ 5/8 ID pickup/plumbing 1/2 NPT pipes, wish my camera was functioning!, extensive mods head to toe
