Anticipating getting my motor finished up this week and then mating the T-5 to the engine and then installing back into the Coupe. I have BBK full length 1 5/8" headers, can I go ahead and install those on the engine before hoisting everything in? Or do I have to wait till engine and t-5 are installed?

One more thing, are the header gaskets and hardware that BBK supplied sufficient? Any suggestions for improvement and reliability?

Install the headers after. They get in the way. I just installed my motor this past weekend and ended up taking mine off to install. Also bbk gasket suck for sealing, I have the same headers and I ended up using a pair of copper gaskets. They say they are good for many reinstalls. Sealed my headers right up. I hate the sound of a exhaust tick from a non sealed gasket
 
did mine a few times now,like @stykthyn said.....also check the welds,one of mine was leaking,after a few gasket tries i found the problem hidden underneath.....i used felpro 1415 i think,no issues now
 
If you have aluminum heads with those ARP bolts, be careful. The bolts were about a good 1/4 inch short and I stripped out one of the thread holes on one of my heads.
