I did mine myself, with a machinist friend guiding me.

I first made a lathe fixture for mounting the rockers. I have an early set which had no
bushings so the first job was to bore the centres, enlarging them for the DU bushings.

Hand reamed to exact size and bushings pressed in, splits to the top. Drilled oil holes
and touched the inside of the new holes with a die grinder to clean up the hole and give
a little bevel.

Sent out to a specialty cam shop to re-radius the faces.

A couple of the adjusters needed a little thread filing so they'd screw through nicely.

The finished product, washed, lubricated, and bagged:
