Can anyone recommend a good full-engine gasket set for a 390? That is, in terms of factory correctness and quality/performance. Or is this a situation like decals where the best route is to buy individual pieces? My car will be driven, and since the gaskets are mostly hidden or painted anyway, I don't feel it's necessary to seek out all NOS gaskets. But I would like keep with original appearance as best I can (e.g. valve cover gaskets).
