I ordered a set of FelPro intake gaskets for my 312,.  I specified for a 63/64 truck so I would get the smaller exhaust heat passage  I received the gaskets and they have the full size 1" square heat passage.  The part number is MS 9361 B1, and it has 45196 in a little box too.  The application says that they are for 55-64 car and truck, 272" -312".  They may have changed their offerings to one set for all applications.  I found I had some extra gasket sets and have a set with the small holes, all metal.  Are the valley pan/push rod chamber cover grommet type washers the same as those for the valve covers?

Thanks,
