The cap includes an elongate cap body structured to bolt to a base to form a camshaft journal bore, and each of a first and a second shaft bore for receiving rocker arm pivot shafts to position the rocker arms at different pivot locations. The rocker arms may be structured to actuate gas exchange valves arranged in a diamond pattern.
