Primary gasket
There are four different primary gaskets in the 42 years of the K-model and Sportster. This is a testemnet to engineering ethic of Harley, that tried to not make changes for no reason. Indeed, the second gasket can work in earlier application, so you may consider the are only three different gaskets.

I think this is
for post-1991 5-speed bikes. It certainly does
not belong on an iron Sportster, but here is a
picture so you know you got the wrong
part.
