I'd reconsider cutting and replacing with sections from the "new" pipe. IMHO, if the "new" pipe is in better overall shape, I'd stick with the plan and R&R the pipes.

I understand that JB Weld can be used to make the bead needed (archives) should you decide to start cutting pipes. Not sure how well it works, but maybe the archives will reveal that. I have read that double clamping can suffice if there is no bead.

And speaking of JB Weld, IIRC, you can repair the pitting on heads with it. (archives). But then again, maybe your heads weren't leaking. So if it ain't broke......

Keep at er'!

Neil.
