Just pulled the head of my spare motor and got it for sale. I always thought it was a 2wd one becase it has a 2wd thermostat housing but............. it is a late sapphire 2wd one - basically the same as a RS500 one but cast by cosworth instead of ford.
So - it is RS500/4WD spec but still has the turbo support for a 2wd manifold - wow!
The head is perfect with VERY little corrosion (it really is amazingly clean - pics will come later) and comes complete ready to bolt on with cams (think they are standard but trying to suss some numbers on them), valves, springs, lifters, thermostat housing, plenum (with spacer plate), throttle body, rocker cover (with breater adaptor), fuel rail and almost brand new original fuel pressure regulator. No sensors/idle motor (need then as spares for myself)
Also the plenum and runners, rocker cover, thermostat housing have been polished and look .
And the best news measures 138.5 mm min - so only 1 skim.
Viewing is welcome and I will post some pics as the ones I took on the camera phone are crap.
Offers invited at the moment but will probably put on the ebay. This head has been in my car for two so can guarantee not problems - it really is amazingly clean!! Only reasong for sale it that I purchased a new head to get ported as I thought that this head was 2wd - and the fact that i have too many spares parts lying around and need some cash for the "slush fund that the wife doesn't see".

And also have a cosworth 205 short motor that the head came off that I am going to pull apart (I need the crank and rods).
