1988 Ram 50 2.6 with air jet valves, 130k miles. I would like to know what no jet valve heads swap directly on to mine so I can start a search. I want simple, no strange parts to adapt or search for. Need my manifolds to fit the new head. No gasket interference, water or oil hole or cam problems. I only want to do this once. The simpler the better. The cheaper the better. Thanks.
