Reputable engine builder in Herts/Beds/bucks?

[Ponk]

Morning chaps.

Hope i've put this in the right place. I'm in need of a good engine builder that's local(ish) to put my bottom end back together for me. I'm based in Hemel Hempstead and the engine in question is a low comp Pug/Citroen 1.6 16v.

Any suggestions?

Cool, thanks for that. I'll give him a bell.

Anyone else have any suggestions?
