Someone here will know. But if not, it's easy to figure out which way it installs. I remember using a straight edge across the timing cover mounting surfaces on the block. I slid the slinger on the crankshaft, laid the straight edge down (accounting for gasket thickness), measured from the straight edge to the slinger, then I went to the timing cover and measured how far the seal stood out from the mounting surface. Then I turned the slinger around, and repeated the process. I seem to remember that the concave faced forward, but I'm not 100% on that.

The oil slinger was originally used to provide lube to the plastic timing gears.These gears were an attempt to quiet engine noise.Roller setups require way less lube and oil mist and splash is all that's needed.Ask any big engine builder.Slinger won't hurt anything as long as it fits and doesn't contact the chain or gears but not needed with roller.

But if you're running a mechanical fuel pump, don't forget the fuel pump eccentric. It still needs all the oil it can get. Especially a one piece eccentric.
