What rocker arms??

Depends on what cam you're going to use.

For instance: Comp Pro Magnums work great just the way they are for flat tappet cams…but if you stick a big roller cam in there with high spring pressures, you’re going to gall the rocker shafts. There are ways around this, like bushing the rockers, and using banana grooved shafts.

FWIW, I use Comp pro magnums that are converted to Ball/cup, and banana grooved rocker shafts from Hughes for improved oiling. This keeps my rockers alive with my small solid roller (spring pressures 210 on the seat and 450 open).

Oh yeah, and Smith Brothers push rods.
