At OF Performance, we've developed our all-inclusive repair & customization tap it right Kit. Designed to be installed over a broken lifter guide bolt without risking extraction. Our kit comes with precision machined lower profile tappet covers, so stock pushrod tubes can be used with no issue. Tap-It-Right, without tapping it at all! Avoid the possible complications you may face in the event of having a snapped engine case bolt, you can now spend more time building and less time stressing.
