***UPDATE—-VALVE COVER CASTINGS ARE BEING MACHINED AND SHOULD BE AVAILABLE IN March. SORRY FOR THE INCONVENIENCE. Our Alloy Valve Covers feature a raised rib (polished optional) and fit all 144/170/200/250ci engines, with stock or aftermarket rocker assemblies. Raw castings can be left as is, or painted by the customer, as shown. Longer bolts are needed if replacing a stock steel valve cover (available below.) Optional gaskets are also available. Optional oil breathers and PCV's are available.
