I'm installing a new ford racing intake manifold(m-9424-p46) this week and I heard I should put something called (tmx black gasket???) in the four corners of the new manifold gasket. On top and on the bottom of the gasket to make sure it doesn't leak. I thought the gasket that goes between the manifold and head should be good enough and didn't need anything else. Any extra advice or tips on this install will help...
