Rocker Cover Gasket

[RoadWarrior]

As part of my engine overhaul, I've decided to take the rocker cover off and do some tidying up.
 
3 questions come to mind:
 
1) Can anyone confirm the part No as 058198025A?
2) Is OEM recommended or are there any better performing aftermarket versions?
3) Anyone got any recommendations for gasket sealant or will any high temp one do?


Many thanks as always
