Are you seriously doing a 7A-GE? The fact that you have to ask which header to use doesn't exactly imply that you've got the knowledge/searching abilities to build a hybrid 7A-GE.

That said, the 20V stock header or a 16V 4A-GE header will work, the latter requiring modification. Two bolt holes on the outer flange of the header don't line up, so you have to weld on extra metal and drill new holes for the mounting bolts I believe. I've seen photos somewhere...if you search you'll find them eventually.

As far as horsepower numbers, I'm pretty sure that you don't use a stock block. I think pistons require changing, and the piston will affect compression, and therefore horsepower. You have a lot of research to do before you take on a project like this.
