Abstract
A modular cylinder head is configured for use with combustion engine block configurations each having different valvetrain oiling pathways. Thus, when used with “LA-style” engine blocks, oil receiving/delivery ports provided by the cylinder head are compatibly interfaced with an oil outlet port provided by the engine block, thus allowing oil to pass from the engine block into the head for delivery to a valvetrain carried thereby. Alternatively, when the head is used with “Magnum-style” engine blocks, the oil receiving/delivery ports of the head are not used. Rather, a pushrod and lifter having internal ports are used by the cylinder head to allow oil to pass from the engine block, through the internal ports of the lifter and pushrod, and into the valvetrain.
