This is a one piece straight guide. To install, insert the undercut end into the block first. The top domed end extends above the bottom of the dished hole about .030" use a 5/16 bolt about 3" long to tap the guide in. After the guide is in place, use a countersink with 1 degree angle to clean up any burrs, or hone the hole. The guide is longer then the stock ones, but there is no need to shorten them. Tappet clearance is .010"-.013" on a cold engine. Can only be used with modern style valves (9180), keepers (9310) and retainers (9330).
