AMS 4B11 Torque/Honing Plate

The AMS 4B11 Torque/Honing Plate is an essential tool when machining your engine block. The 4B11 block is a lightweight aluminum casting. Since the overall mass of the block has been reduced, the controlled stresses of the cylinder head bolted to the block have become an important factor in the block’s integrity. To ensure integrity, we must recreate that stress by using a deck plate when boring and honing to eliminate distortion of the cylinder bore.
