 **Make sure to use the correct gasket for your engine/cover specifics**. \\
 There were changes to the upper feed galley that dictate a specific gasket, especially between 1979-1982 models. \\
+The upper oil feed galley was redesigned during the 1979-1982 and according to the MoCo, the gasket must fit the case design. \\
-**1957-E1982 right cases with the small boss and __upper oil feed oil slot__:** \\
--1976 K and Sportsters original gasket (25224-52), designed with an upper feed oil hole. Updated gasket (25224-52A). \\
--L1981 and some E1982 Sportsters original gasket (25224-52A) original had a single for the upper feed galley passage. \\
-The original gasket was updated in Nov. 1979 with a short slanted slot added to match the gearcase modification in L1979-E1980 models. ((TSB M-778 dated May 13, 1980)) \\
-And the updated -52A gasket replaced the -52 gasket for 1952-1976 models in the -78B catalog. \\
-**1982-1985 and some L1981 right cases with the large boss and __upper oil feed hole__:** \\
-L1981-1985 Sportsters use gasket (25263-81), designed with a long horizontal slot. \\

 It is a cross pattern in the middle and following side to top screws in pattern and this same sequence can be used on 1957-1991 model cam covers. \\
 Since getting all the screws evenly tightened has always been the goal, the 92 torque sequence can't hurt if you'd like to use it. \\
+This will help keep you from snapping screws, cracking the case or creating oil leaks. \\
+Don't try to get to the torque spec all at once. Divide the intended torque into steps using at least 2 full passes (3 is better). \\
+It's a small torque spec but even torque on all screws is the goal, not the spec. \\

+On the right menu, click on "Using a Torque Wrench" scroll down to Technique. \\
+It's safer to use a beam type wrench on these fasteners than a clicker type wrench. \\

+Using this sequence, you will get more of an equal torque around the cover, better fit and less chance of leaks later. \\
