I looked at a spare cam to figure out which valves to
adjust when.

I readjusted the valves and set them to 20/21 or so
(so the 20 would slip in pretty easily and the 21 would
fit if I pushed).

The motor's a bit less clattery. I can't say it is
silent but it is quieter. I think I need a new rotor
since the contacts on my old cap were a bit chewed up
looking. I put another cap I got from a junk yard on
but I guess I didn't grab the rotor, or maybe I lost it
or whatever. If I poke around with a rubber tube in my
ear (poke around with the other end) and there is
some clattering noise coming from the cap of the
distributor.

The car is running much better than before. I'll
try to take pictures of the old head.
