Tick is gone. Won't be time to mess with it until next week, but once I get the ignition module and distributor all buttoned up I'll give her a nice ride and see how I feel about it. I did stick my finger into the drain hole and could feel a bit of gunk down there, but this was also a cold oil change. I expect changing the oil at operating temps will clean it out well enough. Not afraid to waste some oil and filters and give it a few quick oil changes.
