Mine arrived yesterday and looks good. Mating surfaces seem flat with no rough edges that I can see.
Getting prepped to do the swap and watched this great vid:

Thanks D Landy :)
He suggests replacing the oring/seal on the oil cooler which connects into the water outlet pipe:
Attachment 190721
The comment section mentions part# Lr013151 - but I think this is for the two seals on the water outlet itself (which came with the new part).
Googling suggest it may be this one:
ESR1594L
Can anyone confirm?
