Zenith to intake gaskets

[chester rides again]

i have a leak in my bottom zenith carb gasket where the phenolic block attaches to the intake manifold. RN got me the gaskets, but I don't know if i need to lube the gaskets with anything (oil, hylomar...) befor applying the gasket? FWIW, i'm replacing the three lowest carb gaskets at the same time as they will all be exposed during this process.

thanks in advance,
jeff
