dyna rocker cover removal
You may not need to remove the tank completely, just take the bolts out and raise it up high enough to get the bolts out of the rocker covers. Watch the fuel lines while doing this, they can be positioned to allow the tank to be raised. Use a 2x4 block or something shoved between the tank and frame to hold it up. Then remove the six bolts on the top cover, and take the covers off.
Under the covers, in the center of the rocker boxes, there are two bolts holding the breather valve and filter. Remove those and the breather boxes. If you can't remove the bolts, just loosen them completely, they will come out with the lowers once all the bolts are fully loosened.
Then there are four bolts holding the rocker arm support plates. You cannot remove these until you have the lower box loosened as well, and they all come out with the lower box. Note that if you have adjustable pushrods, you may wish to loosen the push rods first, to releave tension on the rocker arms themselves.
Loosen the rocker support plate bolts slowly, while turning each bolt one or two turns in succession, in an opposing pattern, to releave the pressure. BUT without experience, it can be a bit difficult to know when you are causing stess to the rocker arms and support plate. Just take your time.
Then loosen the other four bolts in the corners of the bottom rocker box cover/plate. Again, just loosen these don't remove them, and with an opposing pattern. Once you have all the eight bolts loosened, you can work the bottom rocker boxes with the rocker arm support plates out in one shot. You may have to lift the loosened bolts while doing this to get the assembly out.
Clean all gasket surfaces and toss the old o-rings and gaskets, and use new ones on install. Then just reverse the removal procedure, and torque all fasteners to specs.
If you have adjustable pushrods, then you will need to rotate the rear tire in order to get the pistons in the correct position to readjust them on install. And the pistions must be at top dead center so the cams are also positioned properly. You want to do one cylinder at a time for this process.
That's about it...

EDIT: That drawing OhioSkully posted will help greatly to see the parts I'm speaking of. Thx OS!
