No Toyota engine has ever been interference, including any and all engines from the Supra (5M, 7M, 2JZ). With such a low compression for our turbo motors, it would have made more sense to give the heads more volume (to compensate for valve lift and size). It would also probably have resulted in a better quench area, and less necessity for running pig rich in higher RPMs.
