> I'm putting my 22re back together. Which bolts do I thread lock
I don't recall anything in the engine that requires thread lock. There's at least one oil pump bolt that needs sealer. While I may be wrong, I remember assembly as being very straightforward.
> and which get antisieze? Does the exhaust manifold get antisieze?
Absolutely. That and a bit on the spark plug threads. Can't think of any other place where it's a must. Make sure your fasteners are in primo condition, don't take any short cuts, and your need for little tubes of stuff will be scant. Be diligent with the torque wrenches.
> Do the head/rockerarm assembly bolts get threadlock?
I wouldn't do that. I used ARP assembly lube as directed with their head studs. But no matter what, I'd avoid locktite on the head bolts. If you recheck the torque after breaking in the rebuild, then again with each valve adjustment, you shouldn't have a problem. Again, make sure all threads and mating surfaces are clean, no matter how much trouble it requires.
I'll lock the threads on ring gears and cheap exhaust clamps. Other than that, can't think of any must-use application. I'm sure I'm forgettin' something, tho.

FSM
> Also, any gasket removal advice?
I use a can of brake cleaner and a pick set to carefully lift away as much gasket in one piece as possible. With care and good lighting you can work wonders with the picks. Strips of scrap hardwood (as hard as possible) cut at an angle on a miter saw serve me well as scrapers. Cheap Harbor Freight brushes and lots of fingertip evaluation of the mating surface. Don't do anything to risk the integrity of the surface, no matter how frustrating the process becomes.
Like with the fasteners, accept no compromise - there's only two states: completely smooth and not completely smooth.
I don't care much for gasket sealer, so I took a page from the Old Timer's Book of Mechanical Lunacy and put mine back together using ONLY GREASE on all the gaskets suitable for RTV (except for the half moons, of course). If it didn't work, fine....get another gasket set from Ted and have fun cracking her open again. Good excuse to get that head and cam, too.
But, it worked great! A year later, no leaks of any kind and I'll thank myself when I bust it open soon (yeah, I'm getting that head and cam innyhoo).
