Getting to 0 lash 273 rockers hydraulic cam

Sound real good to me.

The easy way to get .030 is to mark the push rod at the valve cover surface, then turn your half of a turn and see how far the push rod moves.

You may have to give it a minute or two to collapse the lifter. but once you figure out how much of a turn you need on the first one you can just adj all the rest. Make sure you are on the base circle of each one you do!!!!
