Can anyone confirm from the numbers what model/age this head came off please?

 

it came from your G reg 4x4 saff ? LOL anybody really know is it a 92 head or 90 >?

 

Thought the V92 was the year of manufacture?

 

it will have a lug on the side if its a 2wd head Rich,if not its a 4x4 head.

Not sure on them numbers though.




Dave.

 

Dave, yeah it's definitely a 4x4 head

I'm specifically interested to know if this would be a 1990 head with that number, or maybe 92> 'greentop' head, if they are different????

 

Rich
I would say looking at this pic, that heads been skimmed to death anyway
Can't see it being any good

 

if only you could really skim ya heads with photoshop.

 

I bet you had to look twice tho

 

My 4x4 head has the #s VF896090AA YN0643 and its a '92 green top.

 

not when I've only just picked it up from being done and measured Wyn... no LOL

 

well, the Ford Workshop manual quotes cast marking for 4x4 head as V89HF6090AA ...

So is this one I've got technically an Escort one then?
Are there any differences between the 4x4 and Escort heads?

 

Rich,

I will do a search now for one of my previous posts.....about YB prod numbers/dates.......Got a feeling the 4x4 Saph and Big Turbo Es Coss heads are the same.....as all these were built as one batch.

 

Bernie,

If you mean YB engines, then this is the information I have:

YBB - October 85 to July 89....18,990 produced (5,60 3dr and 13,390 4 door -250 excess to build requirements)

YBD - May to August 87......525 produced (RS500)

YBG - October 89 to November 91.......12,515 produced

YBJ - dates as YBG Euro 1504 emission standards (green cam cover)

YBT - March 92 to Feburary 94......5,186 produced (Escort Big Turbo)

Total units built (up to 1994) 36,691 (add 525 RS500 type for a total of 37,216)

My book (The Cosworth Fords - Jeremy Walton) was published
in 1994....so no further information. From then onwards
they produced the YBP (small turbo Es Cos) engine.

 

BINGO!!!!

ON my rebuild engine (1994 Escort Cossie) Y92HF 6090 AA

 

Nice one Doug,
There's the answer to that mystery then! Head's been replaced at some stage... would be interesting to know why, but it's been on there a long time and standard thickness when i took it off..
I wonder what the differences are? Seems odd to change the cast number just for the sake of it if it's otherwise identical..
