Okay, so reading these forums I see that it has been recommended to use an AU head gasket in the EB -

Are the rest of the gaskets interchangeable also? Meaning if I bought a head gasket set for an AU instead of EB, would they all fit or are some different? Stem seals also?

Head bolts too, should I be using EB or AU?

au gasket and head bolts for sure, pretty sure the manifold gaskets too but haven't done them so someone else may confirm.

the difference in the head gasket set from eb to au is, au has different rocker cover seal and different size valve stem seals..

when people say use the au head gasket they mean the genuine mls (multi layer steel) gasket, some aftermarket head gasket sets for au sometimes use a std composite gasket like earlier models...
