I don't know which heads you have on your motor but if you have any type of OEM ford cast iron head (excluding Clevo Heads) ported or not...No... you will get lots of torque & the heads will not work past 4000rpm to 4500rpm due to small ports & small valves (even if you use 1.94 & 1.6 afftermarket valves). On the other hand if you have some nice afftermarket heads with decent ports & they are ported they will work extremly well.
