Hi Bob. It seems maybe that your PO is talking about resurfacing exhaust manifolds instead of intake manifold. The 455 MH uses a lower than stock intake manifold for floor clearance. To keep the floor level the only choices are stock MH, Toronado, or Rockwell Alum. You do need to remove the intake to block the exhaust crossovers. Mr Patterson has gaskets with the plates needed.

One of the previous owners wrote in their notebook that they had the manifolds resurfaced and had a new gasket installed. Eventually, the records state that the manifold was too thin to resurface and just had a gasket installed.

As I have been considering adding the Howell Fuel Injection to the engine (455) I figured I would replace the manifold at the same time. I contacted a mechanic/racing friend of mine for advice as he has replaced many manifolds and installed FI systems. He suggested looking at the Edelbrock Torker ( http://www.summitracing.com/parts/edl-2730/overview/make/oldsmobile ) with the MSD Atomic Fuel Injector system.

Does anyone know if this would, in fact, work on our motors? If so, is there anything special that needs to be done to the manifold?
