We wanted to see if all was good with our valve lift and installed a dial gauge on the tip of the retainer to check it. With a .015-inch shim under the rockers (our heads were milled .015-inch and so a .015-inch rocker shim was needed to prevent the lifter from collapsing), our gauge showed .500-inch lift, right on the money. Our single spring valve springs are rated to .525-inch lift so all is good there.
