340 or dougs headers go in car first?

Noooooooooo. Install headers and then suspend the headers on the side, best done with 2 freinds rather than rope or wire, then drop the engine in. Bolt headers on heads after the engine is bolted to the tranny.

THIS!

If you are dropping the engine in. Leave them in the bags to keep from maring the finish. It's a bit of a balance but not tough.

Bungee cords work well if by yourself.
