Curiosity leads me to ask, assuming with your cylinder head choice this is a compitition engine only, correct? If so why would you want pushrod oiling?
Because he is changing his rockers from a shaft mount system to paired rockers .

You will need to restrict oiling with bushings. Otherwise you will have too much oil up top. So....I would bush the lifter bores.
Can I restrict the oil with the pushrod hole or jet?

My lifter bores are bushed, T&D paired rockers. .080" feed hole in the bushing, Two .110" holes in each tappet, pushrods were about .110". Way to much, motor would only carry about 45psi with the pump relief valve adjuster screwed all the way in. I epoxied my tappets and drilled one feed in each to .040". Worked great. I read about another way which I think might even work better. Press a roll pin in the pushrod.
