There are two ways to know whether you have a Hemi or Non-Hemi Engine. Obviously, the heads are different, which is easy to see by the engine's valve cover. The Hemi will have a wide casted valve cover while the Non-Hemi is identical to the Stamped Tin Clone Valve cover. The other way of know is checking the part number, which is 60363 for the Hemi. Even though these should be a fool-proof way of checking your engine, many parts are interchangeable with the Non-Hemi and 196cc Clone. It's important to know which engine and which parts are in your engine.
