D5244T Cylinder Head ID marks - advice please
 

Hello, hope someone can help, this is my first forum post.
My 2011 XC90 AWD 2.4 200bhp has a broken cam belt at idle. I have removed the cylinder head to find that all off the tappet has smashed out of the head thus ruining it beyond repair.

I have searched for a new head and have one offered to me. My existing cylinder head number is 30731988-009. The 2nd hand head I have been offered is the same number apart from the last 3 numbers. Could someone please advise if the last 3 numbers are the “date of manufacture” and does not affect the casting.

Thanks for your help.
