mag manifolds on 85 ram?

[Dana]

Does anyone know if 1998 magnum manifolds will fit and clear everything on my 1985 d250. I have a couple exhaust valves leaking so tommorow I'm putting on some fresh j heads I've had laying around, and thought maybe the mags and duals would be a small upgrade on the cheap. Sorry for the truck ?, but this really is the only place I visit. Thanks

The 85 manifolds aren't going to give you very much more flow over what you currently have. You need a Large Hole Dakota driver's manifold and 93 Mag Passenger to get max flow out of the J heads. There are no cast iron manifolds that flow better than these!!!
