TQ questions

I'm not worried about the extra EGR port, a vacuum cap will fix that. How would it be set up internally otherwise? Besides the extra port would it be set up the same as the version without that port?
Either way I will not be using EGR. The intake that I have here isn't set up for it, and I've had the original EGR blocked on the original 2bbl intake blocked for years as it is.
I did see that info about 77 440 somewhere else after I posted this thread. I had no idea they had HP 440s as late as 77.
