I know the manifold is Aluminum so when I replace the bolts what should the torque requirement be. Should I torque it while Cold or Hot? 

should I use some removable Lock tite on the threads?

 I would use Loctite #242 (blue).

Are you having fun yet?

I was able to clean up the manifold where you normaly can not get to. also there was some paint missing on the manifold side of the valve covers. There is a bracket on the pass side that goes from manifold to AC compressor and that had blistered paint and rust. That was blasted and painted a two step baked phenolic enamel coating here in the shop today. (If it's good enough for our fighter jets it's good enough for the vette).

I ran out to autozone at lunch and got a can of GM blue engine enamel for touching up the manifold and valve covers.

It still won't be as nice as Chips (crossfire82) under hood detailing but that missing paint and little bit of rust always bugged me.

So now I have 10 days to get the car back up and running before you all get to my house.
