Cast 273 rockers or factory steel rockers budget 360?

Ol'forest said

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?

You use ball and cup pushrods that are the correct length for hydraulic lifters.

The oil to the adjuster gets through the rocker via a hole in the rocker. The shafts need a banana groove across the hole in the bottom of the shaft.

There really should be a hole in the shaft that lines up with the hole in the rocker, but millions of miles have been put on this stuff without that hole.
