That's better. The heads will cross fit, but doing so will mean raising an issue with the hot start. The 426 has a hot start built into the carb, whereas the 400 uses an external unit for which there is no fitting on the 426. If I had a 426 as a parts bike, the first thing I'd try to figure out is how I could use the whole 426 engine. What's wrong with that?
