BHG replacement, need pointers!

[brandonsupra]

My old thread didn't get much of a response, I'm hoping I can get some feedback here. I just found out I have a BHG today...it's pretty bad it looks like a steam factory pouring out of my hood. Anyways I have some questions that need addressing.

Firts of all, which brands are the best for metal head gaskets? Are there any other parts or things one should buy to make this BHG replacement the most efficient?

Secondly, my friend (who's a sort of back yard mechanic owns 2 mark II supras with the 5mge engine) is going to be doing this job for me. Is there any pointers or key things to note while doing this that would be different from installing a HG for a 5mge? He has replaced his head gaskets before, but never a 7mge or 7mgte even which is what I have. What should it be torqued to? any special sealants/head glues or whatever that work better than others? Any other tips are welcomed and appreciated!

Thanks for reading at least fellas, most especially thanks to anyone who can come up with a well described reply to this!
