Hi,it is a Ford ranger header from a 93-94 ranger.Bolt pattern is standard lima engine pattern.Any 2.3 under body header will work on your engine,you might have to add in a O2 sensor with some of them but they fit.Your truck should have 2 o2 sensors,one in the manifold and one in the down pipe.The 95-97 ford ranger header will also work,you just add a O2 bung to the down pipe.

All 2.0/2.3/2.5 heads will physically bolt in place of each other. They all have similar exhaust port shape and placement. All cams are interchangeable as long as they are used with the proper followers. Later model (1995 and newer) roller cam followers cannot be easily swapped onto an older head as the valve stem size was reduced in the newer heads and matching slot in the follower was reduced. Early 2.0 and 2.3 heads have the same small round intake ports spaced evenly apart. They differ from each other in their valve sizes though.
