Head repairs

Can anyone recommend somewhere local (stirling/edinburgh/glasgow/west fife) to get valve guides replaced? Also needing a snapped exhaust stud removed and one spark plug thread helicoiled. The heads are off, so just need somebody who can do the machine/press work.

give these guys a try i have used them in the past and were very good.
