The Holley 241-262 is a trussed LS valley cover machined from billet aluminum, designed to dress up the lifter valley of a GM LS engine with a race-inspired, modern look. It installs between the cylinder heads on LS1/LS6 (10-bolt) engines, is machined smooth on the underside to allow deletion of Displacement-on-Demand, and retains a provision for reinstalling the oil pressure sensor. Note that it is not intended for engines that use valley-mounted knock sensors, DOD, or Active Fuel Management.
