Each PROFORM Grade 8 Header Bolt is permanently assembled with a pair of special washers. When the bolt is torqued to 28+ ft-lbs, the washers super-hardened external teeth bite into and grip the bottom of the bolt head and the top surface of the header. After being self-locked in this manner, any bolt-loosening rotation is blocked by a wedge-locking action created by the washers interfacing, matching cams. Its an uphill climb: vibration that might ordinarily loosen the bolt actually increases the wedge-locking tension, securing the bolt even more. Because this simple wedge-locking method uses tension instead of friction, contact with oil actually facilitates the wedge effect. When changing headers, PROFORM Header Bolts can be untightened with a normal wrench, lubricated, and reused.Features:

Furthermore, they were the first to popularize GM Officially Licensed parts with the popular Chevrolet, Bow Tie, and other divisional trademarks, as well as Ford Performance Licensed products with the Ford (sold under the PROFORM Factory Performance Parts designation).
Proform offers unique tools, alternators, stock harmonic balancers, and distributors; a line of roller-tipped rocker arms with the widest selection of manufacturing processes (stamped steel, cast chrome moly, and machined extruded aluminum); and a complete line of popular and easy-to-use engine builders' tools made to intricate specifications.
Proform Parts are engineered to deliver the optimal balance of high quality and economic price value. These prices are the consequence of a skilled and efficient global manufacturing process, not of cost cutting.
