Very little progress:
I got the side cover off and as I turned the engine over by hand, the #6 lifters moved as much as the #5 lifters, just by looking at them. Did not measure anything, I was in a hurry and it was getting dark.
I did buy a new radiator and an electric fan. Different story. They sold me a 3 row rad, when teh car has a 2 row. As a result, it looks like the original fan would interfere with the radiator. What better time to convert to electric fan and free up some much needed ponies
