srx Base gasket ?

[Blue Devil]

Iam just installing my base gasket on my srx and noticed that the holes the antifreeze go though different sizes 2 of them are about 1/2 inch slot the other one is about a 3/4 slot.my ? is does the longer slot go to the mag side or does it really matter?

the longer slot goes to the PTO
