Gasket sets. Pre 1985 and later than 1985?

Does anyone know what may or may not be different between a gasket set for a 360 prior to 1985 and after 1985.
Reason being is I picked up a bunch of parts unopened for a 360. One of which was a gasket set. 1971-1985.
I am putting together a 1990 360 block with 1975 360 heads. Will I be missing anything that this gasket set doesn't come with?

Thanks everyone.
