Hello

here's a cylinder head i came across and was wondering if any of you can positively identify it.

100£ reward for the answer !!!!

What we know so far :

- There are no markings on the head, apart from a number that is cast into the front of it : 01 12 2100 and below that 157 0
- Cosworth / Hemi Style combustion chamber with mahoosively polished (looks like F1 quality) channels.
- Bronze Valve Guides
- Theres watercooling openings below every inlet and outlet port, also between the exhaust ports. Strangely enough i did see that on FVA's ??
- The split head / camshaft carrier idea has been used on BD's although harvey gibs says this is never ever a BD head.
- The guy selling it to me says he thinks it belongs to a Zakspeed but didnt know if F1 or Capri / Escort Turbo or something completely different...

So what is it ??

My personal feeling is that its from a Zakspeed engine that was used in the capri turbo gr5 back in the day.
