If you look at the on-line photos of the parts in that set, you'll see it has early/later: valve cover gaskets, water pump gaskets, side cover gaskets, oi pain gaskets.

I could not see two sizes/sets of manifolds gaskets - use the later gaskets and "one size fits all".

You might OK with this set of gaskets.
