Thanks for the advice, I do really appreciate it. I probably would've overlooked the fuel rails.
I didn't think about the throttle body either. I can't use a 97-03 GTP throttle body then? I wouldn't know how an adapter would work, but it doesn't sound too difficult or expensive to get it figured.
I do plan on headers while I do the swap and a pro tune immediately after to make sure it doesn't all explode, but gonna do what I can as cheaply as possible.

So I guess my biggest concern was if the head gasket on this Craigslist car was actually blown (probably just a lim gasket, according to my experience) then the heads are still ok, right?
