Thanks Gordon and Bruce. I took the heads off on 4,5,6 today.

Rocker shafts pitted and scratched. Grooves on each end. RSR seals on all of them. Someone's been in here...
Rocker bushings not bad but I'll re-bush too..recommendations?

Cam on right side looks good. I'll probably resell them to cover cost of more aggressive cams.

So here's the weird thing I ran into...

Head 4 is marked 2 on the back and 4 on the outside.
Head 5 is marked 4 on the back and 5 on the outside.
Head 6 is marked 3 on the back and 6 on the outside.

Engine builders..why would they change them up like this?

Also, who can clean my cam tower and maybe machine the surfaces?

Thank you guys for all the help.
