Additional NotesOur ready to fit roller rockers are fully assembled and give the added advantages of being considerably lighter and of a higher ratio than the standard, giving not only reduced valve guide wear but also increase valve lift to 1.65:1 (theoretical ratio). They are manufactured from high grade materials so that quality can be assured. They come ready to bolt on and the only modification required is a small amount of machining to the push rod holes in the cylinder head for clearance but this is all easily explained in the fitting instructions supplied.
