Cheers Dan. I've pm'd you though i've been offered a complete head from a guy in London that might be easier.
Fred, everything was out mate. The horseshoe wouldn't touch it (exhaust cam was 20 degrees out). I'll get some pics of the internals in a mo, but whatever happened to it wasn't good. Somethings slipped or shocked it. Its a shame really as the internals are like new, I can't find a mark on anything. The cams aren't even scored.
