You could pull the good pipe from the bad block as a test. It might be possible to thread a tap into the pipe and use a bolt as a puller. Or maybe drill a hole in the pipe in a place that is easy to access, insert a bolt from the end and weld it in through the hole. Once fitted in then new block the weld could be drilled out and the hole welded up.
Like I said, I've never done it but wanted to share some thoughts. Hopefully someone with direct experience will speak up.

I recently had an 8ba block
thoroughly cleaned by my machine shop and yes, the tube was threaded and I presume a bolt was used as a puller. I was told it wasn't a big deal.
