My harmonic balancer is OK and reads correctly at TDC with Cam pointing to its mark. Thanks for the reminder and I will add the rag to the lower cover opening to avoid having to go fishing.
I have now successfully removed and cleaned up the camshaft and caps, the mating surfaces of the head, the shims and valve pusher buckets, and have removed the old bits of petrified valve husher. My ultrasonic cleaner works wonders on hard to reach places. The camshaft hole for the distributor shaft was pretty well gunked and now it is ready to rock and roll. I cleaned up the groove worn in the camshaft by the old seal with 800 grit, then 1500 grit. there is still a depression, but no sharp edge to cut the new seal. In reading up on seals for the distributor rebuild, I found out that you don't want to polish the shaft to a mirror finish. There are no microscopic nooks and crannies for the oil to stick to an the seal can run dry.
I stuffed a rag between the valve spring washer and the valve bucket sidewall to prevent the tiny pieces of husher from falling down into the guts of the bucket pocket. I used a shop vac to pick up every bit of old husher that broke off during removal. I wish there were a way to replace the valve seals without removing the head, because I am sure they are brittle, too. If I could replace them, then the head would have all new rubber.
