My 323 is a lil monster. Was in a 4spd 4door valiant. just as capable as a 340-360. The thing to do is use the magnum head swap. In effect results are similar to a vortec swap in terms of requirement for change. Use the GM beehive springs from a 3100 series 2 v6 engine. Mopar always had poor heads , but great oiling and rod internal provisions.
