HHD-SEV : Torque Plate for Evolution & Shovel Heads
Head bolt torque can distort cylinders as much as .004". You can't bore or hone accurately if cylinder dimensions change that much after assembly. Rings won't seal well and scuffing is likely if the engine overheats. Prevent these problems by using a torque plate to mimic the stress applied to the head during operation.
This torque plate includes three plates and mounting hardware.
