Boring & torque plate honing
Torque plate honing , involves installing 1-2” steel plate on the block in place of the cylinder head to stimulate the cylinder wall distortion of the block when the heads are installed. By honing the block while similar stresses are applied , you insure the bore will be round when the heads are installed. It provides for a better ring seal and prevents piston scuffing.
