Grind them off if you have to.  They'll come right out after you
disconnect the pipes.
Worst case spot weld a nut to them and back them out.

'84, Westy, 1.9 litre.
I discovered a crack in an exhaust pipe today, front R/H cyl.
The pipes have never been off this engine, which is 18 years old, with
80k
miles.
Am I going to have a problem removing the pipes from the cyl head?
Any recommended methods? pitfalls ?

Thanks,   Steve
