In my humble opinion and previous experience, whichever head you use either the 2.02 or 1.94, make sure that it has hardened seats. Either that or plan on stocking up on lead additive. If you have the 2.02's USE'em! If you want torque, just have the bowels blended slightly and leave the runners the heck alone. That roughness keeps the fuel from dropping out of the flow at low speeds.
I used a set of 2.02's on my 383 stroker motor in my stump pulling 1 ton Suburban. The motor's balanced, Keith Black 9.75's to 1 (Uses Premium), steel crank, good stock rods, Edlebrock Performer RPM and a Quadrajet off my old 400 and a custom cam built by Edlebrock just for my application. The builder was suprised that she pulled 450 ft.lbs of torque with a shade under 400 ponies. Not bad for an old gal and not too high priced either. Just right for this guy.
