I would put the rocker asemblys in a bucket of molasses I part molasses 2parts water,keep in warmish place and in 30days rust will be gone. if you are in a warm aria possible the heads would clean up. the previous help is right on  take the core plugs  out and clean the shafts, also not wise to install on a good engine with out cleaning up the rocker face(some 1 with a older valve grind machine can reface the rockers correctly.) a good way to lose a cam 
my opinion is poor rocker shaft lube causes a lot of came issues.

Too bad!  Often those yards waste as much as they salvage & re sell.. Sad..

Got the distributor from that truck today and when I pulled the intake to get room to remove it those G heads had water sitting in them so they are junk and that pipe wrench made it easy to break it loose.

Jeff take the plugs out of the end of the shafts and clean the inside of them.a lot of gunk hides in there  Carl

I am going to clean them up and install as is and see how it goes,I got another set but they came out of a damp shed and some are frozen up but not nealy as bad as the other two sets in the junkyard. One set sat out open and could not get them to budge and on the other 57 the valve covers were rusted out so I can imagine they are rough.
