Lightbulb 6.7L exhaust manifold fit on a first gen?

Just looking at some manifolds and really like the looks of the EGR ports on the newer exhaust manifolds. Does anyone know if it will bolt up to a first gen or 12v head for that matter?

The EGR ports would make for a very clean and simple WG setup! So for an application like mine where lightning spool is a must I could run 2 external gates to bleed off the excess drive pressure. One set for about 50psi, and the other for runs with nitrous set to open if it excedes 55psi boost.

Just thinking out loud, even if its a silly thought.

I remember reading somewhere about someone doing something similar with a 5.9L 3rd gen manifold on a 12 valve that needed the turbo drop location for installation in a chevy. From what I remember they blended the manifold do the inlet was more rectangular vs round.

It will bolt up, but as mentioned the ports are round instead of rectangle. You could port them to fit though.

If I can find one cheap enough I may buy it and do some playing to see what happens. Thanks!
