From what I can tell by looking at a head gasket set for that motor it looks like all the valves use valve stem O-rings, and the 6 intake valves also so use a added seal.
I just can not tell by just the gasket set if these are umbrella type seals which just ride up & down on the stem, or if they are the positive type that would need the tops of the guides to be cut flat and then the OD of the guide would bd cut to .530”.
