Note:The inside dimension for this valve cover is 3 3/16". This is measured from the gasket surface to the deepest area of the inside of the valve cover. When using this cover with roller rockers and/or high lift camshafts, it may be necessary to modify the inside wall of the valve cover closest to the pushrods so that the rocker arms do not rub the inside of the valve cover. If holes for pcv and breather are added, it is recommended that a machinist makes the holes in a milling machine to avoid damaging the valve covers.
