Intake gaskets wicking coolant

Were the heads surfaced excessively? This could be causing problems because the mating angles of the intake and head are wrong. As suggested, put the intake on dry with no gaskets and check the clearances front and rear. You may have to have the intake angle milled by a machinist to correct it, if this is the problem. DO NOT attempt to correct it at home with a grinder, you will end up with an expensive door stop.
