Was able to accomplish a few things over the long weekend. I finished cleaning out the carbon from the valve gallery, cleaned the cylinders to remove honing dust, coated the cylinders with oil to avoid rust, cleaned the bearing journals, and cleaned out the valve guides. I also re-installed the valves, with a little help from my daughter (didn't think to grab a picture!), and set the clearance cold. I added 0.002 to the specified clearance on each valve, and will re-check with the engine warm and idling once it is all back together.
I also have a slight water pump mystery. In the interest of thoroughness, I took apart my water pump to inspect and rebuild. I also disassembled a brand-new pump I had on the shelf to compare. Interestingly, the existing pump doesn't have any casting numbers, but the one off the shelf does. I am assuming my spare was an original pump, and the one on the car was an aftermarket replacement. That's just a guess, but it makes sense to me. I'll re-assemble, paint, and install the new one, with the correct spring cap oilers installed, then rebuild the spare in my spare time.
