TD6 CYLINDER HEAD

Hello again guys
Can anyone out there clarify if any td6 cylinder head will fit on any td6 motor.
I inquired to a number of companys in the UK who said they had stock but when i supplied the casting number off the head, all of them said they had nothing to match.
Starting to sweat......Paul

If the head is off a Td6 or BMW M30 engine it will fit.The casting number you sent could have been a batch number not part number. Pat
