351-408 swap with raised port heads what header

[RobDodge]

I’m actually working on a 2002 and will be using a tubular cross member along with a front and mid plate to mount the engine
Looking for recommendations on what headers will fit

How raised are the ports? I have raised port heads, and the factory replacement BBK longtubes work fine. I'm kind of thinking that if are running enough engine to require a front and mid plate then you need a giant header.

Looking to use at least 1 3/4” if not 1 7/8” or larger

Windsor block + raised port heads + 2000 platform + mid plate engine mounting = header modifications
@geoklass may offer some insight on this.
