This Omix valve cover is specifically designed for Jeep vehicles equipped with the 4.2 liter (258 cubic inch) AMC engine. It covers a range of model years from 1981 through 1987.

Do I need to buy a gasket with this valve cover?

Yes, a valve cover gasket is required for proper sealing and is not included with this valve cover. Omix recommends using part number 17447.03 for the valve cover gasket.

What does 'for use with studded rocker bridges only' mean?

This means the valve cover is designed to work with a specific type of rocker arm setup where the rocker arms are held in place by studs. If your engine uses a different system, you may need to purchase additional parts to make this valve cover compatible.
