 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. \\
