6cyl intake swap

I have 2 6cyls laying next to each other on my floor. One is bad (came out of the Scamp) and one is good (came out of the Duster and is going into the Scamp). I took the 904 off the bad engine and put it on the good one today. That went pretty well.
Next on the agenda is to swap the exhaust manifolds. (One is cracked most of the way through, and of course its on the good engine.) I've never done this on a slant six before, and it looks like a major pain. Is there anything I should know before I do this? Any tricks or cautions? Open to any advice you might have.
Thanks
