G body v8 swap with headers

[Stuart]

I've been doing my research on swapping my gbody to a v8 so most of the stuff I have a good idea on. I was just curious on what type of headers to get. I would like some long tube headers but will they fit and not run into anything on my car? Thank you!

We will need more info before we can even begin to help.

Which G-body? Year?
What V8? What Transmission?
