360 into 64

I would kill me to grind on an engine. I guess those are my options though since I can't afford new headers. I wonder about the dakota manifolds though. Would they fit right? Is it too hard to hook up exhaust with those in a barracuda. I suppose people have done it. I might have to look at junk yards around here. It kills me to cut fenders too, I guess I could modify the k but I still don't like it.

Thanks alot for the help
