I snapped 6 out of 8 so had to employ various extraction methods.
The most successful was shed loads of penetrating oil, a bit of heat (but let it cool a bit, those studs will be like toffee otherwise! It's the variance in expansion between the stud and the block that cracks the rust. Not that the stud is hot) and Molegrips.
Clamp the grips as HARD as humanly possible, and then start with the tiniest of back and forth movement. It felt ridiculous because i was moving fractions of a millimetre to begin with. but just keep going and don't get impatient.
I freed up 3 like this.
1 I filed to a flat and got a crescent spanner on it.
2 had to drill and re-tap.
And replace them with stainless studding for the love of god!!
