Did you sleeve the head bolt holes, or port the wall between the intake ports so much that the cylinder head rocker shaft bolt holes were thin? If it is thin there, it will break through after the oil pressure expands and contracts the port wall. Did rocker shaft bolts or studs puncture the thin intake port wall? One tiny hole anyplace will send oil throughout the engine? Yes, I speak from personal experience. Puddles of oil.
The bottom of the intake gasket is oil soaked. If you bolt the .008 side down with the other side tight you may end up with with a gap at the bottom of the intake. Set the intake back down with no gaskets or bolts and measure the top and bottom with feeler gauges on all four corners.
