The physical fit's the same, but you need an exhaust that clears the oil cooler, and the pickup and generator parts are, I belive, different. If you want to use the FI on it you're in for a monster job, but if you want to use carbs then it's just a case of swapping head components to make the fit. This is all a bit vague, and probably not complete, but nobody else has answered so I thought it's better than nothing, don't take it as gospel. I only read up enough on it to decide it's not worth doing tbh...
