Get a shorty 9/16" "Flex" socket (short socket with inbuilt universal joint,) as it makes the rear screws so much easier.
Use LocTite #272 or nothing on those screws. Torque to 19-21 pound-feet.
A light, even coat of RTV copper on both sides of the gasket won't go amiss.
If you can, replace with silicon bronze screws - better retention of strength over heat cycles (get them from Fastenal.) Also, be sure to reuse those little "dish" washers that came off of the screws. If you can't get silicon bronze fast enough, replace with SAE Grade 5 screws (SAE 8 will lose strength too quickly - I have verified this experimentally.)
The collector stud nuts should be threaded 3/8"-16 - I don't think that changed (although I could be wrong. Please let me know if I am.) Replace with brass if possible, SAE5 if not (if they're metric, try to find ISO 8.8 nuts - for the same reason as the SAE5 screws.)
I'm sure there's more that I'm not remembering right now - it's late. I've covered this in detail several times before, tho, so search for my posts on the subject.
