I used the same exhaust and intake gaskets that the car came with because I was carefull with them. They have been on and off at least 5 times but the graphite gaskets without silicone will last quite a while if you take care of them.
I didn't use Anti-
sieze but if you find some "never-sieze" please let me know!
I didn;t use loctite anywhere.
I used GM Teflon gasket sealer on the Head bolts but not sure if I needed to.
