Re: '55 engine back to life! Mostly worked...

Here is some more info.
After being gone a week, I started it up again to warm the engine then drained the break in oil. Also drained the water in the radiator and filled with ~50:50. To see what was in the oil, I drained it through a white t-shirt and you can see what was left. Nothing really solid, almost graphite like in texture. Fished around in the old oil with a magnet and nothing significant was there. Also stuck the rod with a magnet on it inside the oil pan with similar results.
Filled with 5 qts of Rotella T4 15W-40 and for kicks took off the rocker arm covers to check them out. Oil was evident throughout but I was shocked to find a valve keeper laying in the passenger rocker arm! During assembly I realized that I somehow lost one so I bought some more and replace some of them with the new ones. I checked carefully and every valve still has 2 keepers, so somehow the lost keeper was 'lost' inside the spring and worked its way out.....
Started it back up with an OTC brand oil gauge Tee-d to the existing pressure sender unit. Engine runs great. Oil never got close to L and temp was solid.
Here are some oil pressure vs rpm measurements:
RPM Oil Press - psi
450 30
700 50
900 50
1000 57
1500 62
2000 68
2500 72
3000 78
Gauge on dash looks good to at low rpm so I feel good that this is working properly.
One lingering problem is the transmission. Recall that the driveshaft is removed. When I started it today, there was the metallic gear 'meshing' sound. I moved the shifter from Park to Neutral and it got a little quieter. When I moved it to any other gears (D, L, R) there was no objectionable sound. As I came back to N, it started again. It sounds just like a standard transmission car when trying to get it in gear when the engine is not quite at the right speed for the clutch engagement. Sort of repetitive teeth to teeth hitting sound. I very slowly moved from D to N and the sound went away and was gone from N to P.
Any thoughts on this? the car hasn't been driven in 2 years. My next plan is to connect the driveshaft and take the car around the block but don't want to do any damage if there is something I need to do first with the Ultramatic
