They should make good torque in the lower rpm range, up to the torque peak anyway. This is not necessarily a bad thing if you are wanting a good stout street motor. At some point in the upper range of rpm's, the intake ports will stall and the motor will nose over. Most of those double hump heads are around 165cc's intake runner volume, while you need somewhere around 200cc or a little larger runners to support a 383 to 6000. If you're going to limit revs to under 5000, then the humps will work fine. It won't be a race motor, but it will make good low end torque to pull a heavy car around town.
