I like that picture too, the old wood boiler was really roaring that day.
Four inch drop header...that will be a thing of beauty when you are done. I hope you have some good 36" pipe wrenches, and probably some cheater pipes to go along with them. 4" is tough to handle, and not many places carry the fittings. The steam guys where I work use Loctite 567 thread sealant on the big fittings. It is more expensive than your average pipe dope, but they said it has proven to be a good product.
