Intake Leak Into Lifter Valley???

Manifold has been off a few times, and every time, the gasket "crush" appears to be all around. But I'm consistently oil fouling the same three plugs. Clean them and again, the same three!

Engine runs beautifully. Is there a method for checking intake manifold sealing/leakage by pressurizing or ??, so as to accurately eliminate it as a probable cause? I trust my eyeballing the gasket, but it's possible I might be missing something.

This has been going on for a long time now. I'd sure like to have 8 dry plugs so I can begin fine tuning mixture settings.
