Intake Leaking Oil

Ok seams like I need the intake milled on the bottom as I only have .024 clearance between the wall and intake with .060 intake gaskets.
But I found some Cometic gaskets that are .188 thick, part # C-5566-188. Instead of stacking gaskets and it would raise the intake further away from the china wall.
On my Magnum heads the intake bolt holes go all the way thru, no bottom.
My head gaskets are .040 Cometics.
