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.

Due to the early manuals NOT having torque specs for these screws, many developed a “torque stop” in their wrists and elbows.
However, in order to develop the “feel” for when to stop, you have to bend or break some screws first.
Do not try and stop a leak by tightening the screws any harder than you would installing them in the first place.
Click Here to read about, Using “Feel” While Tightening, on the torque wrench usage page in the Sportsterpedia.
Caution: Too much torque on fastener's can create a leak or make a leak worse than it is.

For those who would like a guide to proper torque on the screws, specs are below.
It's always a good idea to clean the screw threads and the threads in the aluminum case before using them.
Any dirt/oil debris in the threads WILL change the torque that you actually apply to the screws.
You should be able to run a screw in each hole in the gearcase before installing the cover and bottom it out by hand without any binding or hesitation.
If not, the threads need attention before proceeding.
If you can't blast the threads clean, Click Here to see the article in the Sportsterpedia on chasing threads with a tap or thread mender tool.

• Cam Cover Screws:
  • 1957-1969 FSM: There are no torque specs or sequence for cam cover screws other than “tighten all screws evenly”.
    • Snug plus a nudge is a general rule.
    • Use 1970-1985 specs for best results (80-110 in/lbs).
  • 1970-1985 FSMs:
    • Tighten all cam cover screws to 80-110 in/lbs evenly.
• Generator Bolts (1957-E1984): 1957-E1984 FSMs have no reference to generator bolt torque.
  • Snug plus a nudge is the general rule.
  • 70-85 FSM makes no distinction between cover mounting screws and generator mounting bolts.
• Oil Filter Housing (L1984-1985):
  • Tighten bolts to 13-16 ft/lbs
    

The only sequence for tightening the cam cover screws in Ironhead manuals is “tighten all screws evenly working opposite from one another”.
That's basically referring to what is commonly known as a “cross pattern”. Trouble is, the screws are not all in the position to accept a cross pattern.
Some are on the sides and corners and you can mess this up tightening the wrong ones first or last.
Tightening one screw effectively loosens other screws so the process is still a little wanting from the manuals.

It wasn't until 1992 that the MoCo included an illustration in the FSM showing the sequence to use for torque on these bolts.
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.

It's safer to use a beam type wrench on these fasteners than a clicker type wrench.

Below are pics with the adapted sequence shown. Use at your own discrepancy.
Using this sequence, you will get more of an equal torque around the cover, better fit and less chance of leaks later.

Easiest way to install the cover is to cut a few pieces of threaded rod about 3-1/2” long (or cut heads off long 1/4“ screws/bolts) for cover “holders”.
Insert a rod by hand into two or three mounting holes turning to get several threads in (it doesn't have to get tight).
Install the cover gasket and cover over the rods and push lightly on the cover to take up any space to the gearcase.
The rods help the cover come up evenly without binding anything.
Install several mounting screws in unused holes to “just snug” then remove all the rods and install all the other mounting screws “just snug”.
Then use the torque specs and torque sequence above.
