Have you considered using Comp Cams Ultra Pro Magnum™ Rocker Arms?

Has anyone tried these with a large solid flat tappet or hydraulic/solid roller cam?

They look like a high quality part, and they come bushed. Not cheap.

use them in my small block mopar 430 build
very happy with them - alignment was best out of all the rockers I tested - HS, crane gold and these.

The sweep was the best also - they even allowed a 3.8 pushrod in the eddy head without grinding. The HS and cranes did not allow this -

this was for my application and another 408 with a similar setup - same results.

close up you can see there is a proprietary coating on them - some dimpled coating that is very slick.
