Headgasket K series

Can anyone recommend any good Rover specialists to replace a headgasket on a 200Vi? Preferably in the Midlands area.

Is it really necassary to use a multi-layered one? All the garages I have contacted so far say they only use the normal single layer gasket. One garage said they give a 12 month guarantee which sounds good, although I wonder if they keep their promises.

My original head gasket has lasted 86000 miles so I would've thought that it would be fine?

As long as it lasts me another 20-30k miles without major trouble I will be happy.

Ive managed to find someone who will fit a multi layer Land Rover HG. My only concern with this is that I have heard that it can reduce compression and hence a loss of power. Any thoughts on how noticable the power loss (if any) will be?
Thanks.
