OK, my shop manual doesn't specify, so I just rang Ted Schumacher.
His quasi-authoritive answer is that through the end of '70, the
Spits used cam bearings, and the later engines (both 1300 and 1500)
did not.
You might want to check with Ted Schumacher at TSI Automotive in
Pandora, Ohio. His number (so that you don't have to go to the Monster
list) is: 800-543-6648 for orders and 419-384-3022 for help.
