Hello all -- in finishing the head swap I noticed a part I need, but can't locate on the HTK. It is a cooling system "spiggut" that is on the front of the head, intake side. It connects to one of the 2 small coolant hoses.

problem is the one from my original 88 m5 head is too small to fit in the new old stock head that is dated 86. Any help would be greatly appreciated.
