Measuring pushrods

You should also use a "checking" lifter which you can adjudt to the preloaded lifter height for your lifters. Then roll the engine over and check rocker valve wipe pattern and to set the pushrod length. This is the best way to set rocker adjustment to achieve the max valve lift. If you have the rocker adjuster set goofy and measure for a pushrod with lifter preload, the valves may not open as far as you think they are. Plus the wipe pattern may be off and could trash the guides over time. Hughes engines has a good write up on doin this. And you should! You paid good money for your engine. The more accurate and consistent your valve timing is means power and longevity.
