 The measurements are based on the .053 lift specs. Also, take note that the predominance of the intake valve opening occurs on one rotation of the flywheel and the predominance of the exhaust valve opening occurs on the next rotation of the flywheel. It takes two full rotations (720°) of the flywheel to complete the four-cycle process. (This view of the flywheel would be from the right side of the engine.)

-==== DON'T INSTALL a 91-99 CAM COVER GASKET ON A 2000-UP MOTOR!!!!!!! ====
-The 91-99 cam cover gasket has no business being on a 2000+ motor at all. It will cause you to lose all oil pressure. ((aswracing of the XLFORUM http://xlforum.net/forums/showthread.php?t=2079110&highlight=oil+tank&page=14)) \\
-The 2000+ gasket supersedes the 91-99 gasket. In other words, it can be used all the way back to 1991. \\
-Most companies completely dropped the 91-99 specific gasket and only offer the one that can be used from 1991-present. \\
-Either James Gasket hasn't done that, or they may have some old stock. \\
-The 1991-1999 lifter feed galley is an internal rifling hole in the case. It's drilled thru the case and only open to the cam cover via the center port to the pinion bushing. \\
-The 2000-up lifter feed galley is external and it takes both the cover and the case mounted together to make up the feed galley. \\
-So 2000-up feed galley is split in half between the case and cover. The slots in the 2000-up cam cover gasket mate to both the case and the cover. \\
-If you have the correct gasket on there, oil would be forced (between the cover and case) to all the lifter feed holes and piston squirters. \\
-With the wrong gasket (1991-1999), oil pressure leaving the filter gets into that (now open) galley. \\
-Then the oil will blow into into the cam chest, therefore bypassing the lifters, piston squirters and rod bearings. \\
-The oil will simply cycle from the oil pump to cam chest to oil pump and back to the oil tank. \\
-The oil light will stay off so you'll get no notice before moving the parts start oil starving and making noises and worse if the noises aren't heeded to quickly. \\
