First thing, spray them with some penetrating oil. I'd do that for a while and see how they rub down. I'd probably go over it lightly with some oily emery cloth, but not be too aggressive.

Given how that one looks, you might consider getting two new ones... Have you priced machine work on the other head yet? How much? I know you're just trying to get an old engine back on the road, but I'm looking at these: http://www.ebay.com/itm/NEW-PAIR-35...NLESS-VALVES-906-062-/271057279800#vi-content
Yes.
Oh well. I would have marked it, but the procedure in the service manual for installing a distributor without marking it made it sound pretty easy to install and easy to see if it wasn't in the proper alignment.
Anything else I should know for reassembly? The LS motors are considerably easier to work on IMO. The instructions for setting the rockers given in the service manual is to get zero lash and 1 additional rotation clockwise with the valves closed. That sounds about right?
Also, the torque spec for the head bolts is 22 lb-ft + 55-75 degrees (depending on the bolt)? I searched around a bit and it seemed like people were doing that or ~60 lb-ft. Either way, that seems a bit loose for a cylinder head, although I've never worked on a SBC before. LS head for instance is 22lb ft + 90 deg + 90 deg.
