Question about 4027596 heads...

I bought a set of these heads too, But one got broken during shipping.
The seller sent me another one, But on the Deck facing,I have five extra water ports, one in the middle near the intake flange,and two on either side of the second and fourth head bolt near the exhaust flanges.
Will the extra ports make any difference in how the engine runs on that bank if I use it?

Do you mean holes by the exhaust ports?
