I have a 10vt engine, now can i just get a 20vt head and put it on there, or is there some sizing issues. on the cummins 5.9 i've put a 24v head on a 12v block but not sure if its the same. enlighten me please!
The injection system is different, as the engine managment, the ignition system, and the location for the intake manifold. Your best bet is to go for the swap. waaay easier, and probably cheaper!
