Nice to see you again!

The only wet hole is the d/s lower hole, you can feel this with your finger inside the hole... the others are blind holes, if you pack sealant where it isn't needed you could push the bottom of the hole out and damage the block...

You can match that little bit and grind it if you want, if you line it up before tightening the bolts it won't be like that. As for the w/p's, this is how to tell a higher flow vs a standard flow pump tight is high flow, a gap like the flowkooler is lower flow... FYI, flowkooler now has one...
