The spark plug holes must always be clean prior to installation otherwise, you may be twisting against dirt or debris and the spark plug will be under-torqued, even though your torque wrench indicates the proper torque. In short, over torquing can cause severe engine damage. The most dangerous result is pre-ignition when the heat dissipation is reduced due to metal shell stretching by over torquing. Examples include plastic or aluminum brackets that are installed to the outer valve cover fasteners, and that run parallel to the valve covers. Stretching of the spark plug metal shell can break the inner gas seals or cause a fracture in the spark plug insulator.

Proper torque specs for both aluminum and cast-iron cylinder heads are listed below. As a result, the firing end of the spark plug can overheat and pre-ignition can occur. A spark plug that is under-torqued will not be fully seated in the cylinder head and heat dissipation will be slowed. Torque directly affects the ability of the spark plug firing end to dissipate heat to the cylinder head. Torque is one of the most critical aspects of spark plug installation.
