Bspt male iron.
What are the likely chances of getting one of the plugs out in more piece without damaging the stack?

A few applications of Penetrating oil and some heat (LOTS)with a large spanner and extension bar....It should fly out .

Personally, I'd give it 50/50. It's been in there a looooooong time I'm sure. It is in great condition though, so that's going in your favour.

100 years old 3" steel always unscrews with 60's and a scaffold pole if heated enough.
Yes of course and it could also crack if the casting has any flaws/weak spot, especially under heat, only ever done 4 and it's 50/50 so far. Though as suggested, it's clean and in good condition by the looks of it.
Could also slow core the cast and use a McAlpine Mech boss.

Drilling the plug and slitting it is another option that works well.
Jobs like this require you to FEEL what is happening... Not a all hell and no notion attack.
Really .... would never have though about that
As they say slowly gently catchy monkey ..... I think my years in the trade have well taught me that 'touch', especially with years of working with old cast soil pipes/cast and copper bath and sink wastes etc up here in the old Glasgow tenements. Still doesn't stop the casting, that may have internal weakness, cracking under the stress sometimes. I have a lovely pair of long arm stilsons hanging in the garage that I use specifically for that job, don't come across those cast bosses that often though.
