Cast 273 rockers or factory steel rockers budget 360?

There is no reason to use cup adjusters. You can’t just screw them in and go.

I’m baffled that people still advocate for stamped rockers.

I have loads of NOS lifters, a set of stock hydraulic push rods, what should I do to use the 273 rockers? Replace the rods or adjusters? Also I'm assuming standard rocker shaft is ok, but what about oiling to the top end of the push rods? how does oil get in through the adjusters?
