Thoughts on this oil seepage

So my drivers side valve cover was leaking a bit of oil. I replaced the gaskets with cork ones. Lately I've been seeing more oil pooling on the intake manifold where it meets the head. Before I pull the new gaskets out and replace them again, do you think the leak could be coming from the intake manifold gasket?

You can see a touch of oil on the bolt head on the valve cover but not much. Most of the oil is in the valley on the intake manifold where it meets the head so my thought is that I need to pull the manifold and replace the gaskets.

To clairify, I had my shop replace both valve cover gaskets while they were installing the Sniper unit and I'm *guessing* they used the proper sealant. I'll do the next gasket replacement myseif.
