Billet valve cover that fits Honda GX340, GX390 and big block NON-HEMI engines. The billet valve cover features integral cooling fins to shed the heat from the valve spring chamber therefore increasing the life of your valvetrain components. This valve cover also has a o-ring seal so you don't need that leaky stock gasket anymore. Also, this valve cover is taller than a stock valve cover so if you are using roller rockers or wanting to use roller rockers they will clear our valve cover.
