Are you sure its F1?
& not an AMG-type road unit?
Is it one of a pair from a 12, or singular from a 6?
Do the major dimensions/fastener pattern match known production blocks?
too many cylinders? why?
clearly a 5 cylinder head.
one head of a v10 engine.
Cosworth ran many V10 engines.
Identified as a cosworth head.
why would it be a 6-cyl or 12-cylinder AMG head which is of another manufacturer and is missing a cylinder to be v17 or i-6?
The Zetec - R VJ block was a pneumatic valve head/block.
Ask me it would be a Ford Cosworth Zetec blok out of either a Minardi or a Stewart, perhaps when Stewart became Jaguar.
If the head is hard to identify because of missing codes or something like that it could be an indication it actually is part of the custom-made cosworth blocks for Stewart GP, which were slightly tuned/different to the 'normal' Zetec V10 F1 engines.
In 1999, Ford bought Cosworth and built a 'new' V10. Could even be this one, but it's def. not older then 1997 and not newer than 2001.
The exhaust ports on the block shown on the OP seem just 'minimally' more 'oval' compared to the 'normal' Zetec-R VJ v10 (though that may be optical illusion).
That could indicate thus to either the Stewart GP blocks (as a custom cosworth engine was the deal back then), most notorious the 1998 ones, or the overhaul in 1999/2000 when ford took over cosworth.
