I'm not a big fan of rtv silicon for these applications, have had great success with Loctite 518 flange sealant. Get the surfaces nice and clean, apply a small continuous bead, tighten bolts evenly to spec, then let it cure before running the engine. If using the gasket just apply a smear to both sides.
