Front "China wall" sealing issue on SBM
Sand the aluminum Intake china wall seal area with 180 grit sand paper to give the RTV a place to bite.
Of course Brake Parts Cleaner all sealing surfaces, no oil films.
Then Aviation Sealer on the intake manifold mounting Bolts and threaded holes as they go into the oil side of the block.
I would sand the China wall area on the block with 180 to get down to good clean raw iron to help it seal for good measure too.
Good Luck
