I know Barney Moravitz a Pontiac Stocker and SS race in San Antonio used to feel a torque plate did not really help a Pontiac block and he had his own machine shop,and did most of the heat treating on the 58-62 forged rods Butler sold before we have good forged rods.
That said my machine shop uses one.
