lifting, height of the tail rotor with respect to the main rotor hub does affect the roll - I agree with AC that the Huey T/R was set high to reduce the effect.
Nose wants to yaw right, and tail left, because of rotor torque.
Tail rotor forces tail right to counter this.
Now you have a side force making helicopter want to move right (tail rotor drift), so we introduce left cyclic to counter it.
If the tail rotor is lower than the main rotor hub, this creates a force couple (left from M/R hub, right from T/R when viewed from the rear) which rolls the fuselage left until an equal and opposite vertical couple formed by lift (up from the M/R hub) and weight (down through the CofG) is reached.
The closer the tail rotor is to the M/R hub, vertically speaking, the less the rolling couple.
The tail rotor on the Huey is high-set, but not as high as the main rotor hub, particularly with an aft CofG, so there is a roll because of it - slight disagreement with AC there - but it's certainly lessened by the higher mounted tail rotor than if it was just on the side of the boom.
