if the torque plate does simulate the forces, then i guess it would minimize the distortion caused by the assembler that wouldnt be as methodical.
Torquing the head in a specific order is meant to ensure the head lies flat on the deck, and to evenly distribute clamp loading.
The torque plate helps simulate the forces exerted on the block, specifically the threaded holes for the head studs/bolts. These forces have nothing to do with how the head will lay on the block.
