If you knew you could seal it properly with the cork, that's fine. The key is coating the inner portion with silicone so it doesn't weep through the cork. Cork works good, but for so long. Every mechanical shop rtvs that style of intake nowadays.Well, I wimped out. After cutting the rest of my samples open at 96 hours and finding the same thing as above, I went with the Fel Pro cork end gaskets. Used RTV on the ends and applied Permatex gasket sealer to gasket and metal surfaces and dropped the manifold on it. Also put end wall shield plates I fabricated on to minimize oil spray on the joint areas. The more I thought about trying to separate Right Stuff and cleanup if it leaked again, the less I liked the idea. Stuck with what I’m comfortable with. We have crappy weather now so may be a few days before it gets tested.
Certainly a possibility of a blowby on the front crank seal , or timing chain cover corners, brake clean it and recheck
