273 adjustable rockers need refurbish.

Quoted by whom? Gary at Rocker Arms unlimited? If so, send them to him. It's a no brainer. He is a legend genius and what you'll get back will be better and stronger and nicer than anything in that price range.

No one gives the stock ductile rocker credit, but they are STRONG. I wouldn't be afraid of a .650 lift solid roller on some properly prepared and if Gary is doing them, they WILL be properly prepared. If that quote was not Gary, call him and send them to him. He KNOWS his stuff.
