All the above sets contain:
- intake-manifold to exhaust-manifold gasket
- intake/exhaust manifolds to head gaskets
- exhaust-pipe to exhaust manifold gasket(s)

The Classic Parts set includes two styles of exhaust pipe gaskets (to fit all years, 54-62).

You might want to buy two sets. The modern manifolds-to-head gaskets are thinner than the original gaskets and less forgiving to mismatched surfaces. You would then need to have the mating surfaces on the manifolds planed or hope that a double thichness of gaskets will work.

Also, it is not uncommon that the intake-manifold-to-head alignment rings have been mangled, it might be a good idea to get a set of alignment rings.
