This listing is for a single #160 lash pad. A lash pad is the puck that goes between the toe of the rocker arm and the valve stem. For 4 cylinder L engines they use 8 all total. For 6 cylinder L engines they use 12 all total. If you need a complete set of lash pads be sure to put the appropriate number in the quantity box of your order form. Valve train geometry is very critical on all L engines. This is determined by assembled valve stem height, in relation to the height or distance from there to the cam lobe, the size of the lash pad, and the size of the rocker arm. If a head is set up properly then you only use 1 size of lash pad for all the valves in the head. Be advised that not all automotive machine shops are well versed in the proper setup of L engine heads. If you can't find a shop in your area to set up your head properly, you can always send us your head and we can definently do the job. We can do both stock and high performance setups including porting and polishing. We carry all sizes from .160 (one hundred sixty thousandths) to .190 (one hundred ninety thousandths) in stock and can order many other special sizes above and below those numbers. Lash pads come in every ten thousandths from .150 and up. These lash pads will fit both the 6 cylinder L series engines and the 4 cylinder L series engines as well. Stock sizes for stock grind cams are also available and we handle those as well. See listing. These are temporarily a special order only. Please allow an extra week for delivery. When you order one of our custom ground cams we'll let you know what size it takes at that time. We know what size of lash pad goes with a particular cam PROVIDING that your head is machined properly. The early 1980 720 pickup used the L series engine which has the intake mounted on the left side of the engine whereas the later version went to the Naps/z engine which has the carb on the right side. We also sell rocker arms in this section, high performance valve springs, and high performance retainers. See listing Last update 04/10
