Good morning,
Water in the oil is an indication of leaking from the head gasket.

When the head was removed, you had it planed, which is the correct way of doing it, but did they also check it for cracks? Cracks are common and will cause this.
The block generally does not warp unless there was a severe overheating condition.
The other thing is the head bolts. Did you replace all the head bolts? If you used the old bolts, they may have failed to keep the head secured to the block. They are called torque to yield bolts and are 1-time use only.
