Replace rocker shafts for sure
way to go mini
make sure the needles are all ok
spin them around and see how they feel
repositioning will give you fresh needles
I did like the ras case hardned shafts vs the induction hardened ones
there were a lot of those inductioned hardened ones that would Rockwell ok but it was so thin it would Brinell through
and chrome...
ok with bushings
