if you are talking about the intake hitting the valve covers at the runners,, it is common on after market valve covers and after market intakes on a small block mopar,,
set the valve cover on the head with out the valve cover gasket,,mark the edge of the valve cover with a marker around the runner where the intake is sitting on ,not allowing it to sit down on the head competely,, you will have to grind that area of the outer lip of the valve cover to make it sit down on the head competely,,,make sure not to gring to much,once the valve cover sits down completely , a new gasket will seal it up
