Reputable Machine shop in Herts/Essex/North London?

[caduceus]

As the title suggests - can anyone recommend a good machine shop to check/replace cam bearings, check/hone cylinders, core plugs, etc on my 4.5 Chimaera block?
Just doing a refresh whilst the engine is out.

Cheers all

I beg to differ, regarding G'nays

Could you elaborate please?

Has anyone had any dealings with, or heard anything about 'Power Units' in Hatfield? Are they any good?
