There will be 2 additional hoses going to the radiator.

Are you sure you got all the oil out in the first place. That's not easy to do.

I have used dishwashing soap to flush them before. Just be sure to get it all back out so it doesn't suds up on you.

How long has the engine been running after repairs?
Was the cylinder head pressure tested for cracks when it was out?

When the head gasket was damaged or during repairs, water could have gotten to the crankcase and draining would not remove all. A little running would clear out the water if the head gasket job had solved the problem.

If you get oil in the cooling system, it's not going to come out on it's own. You need to use a grease cutter to break it down and flush it out.
You said you put a brand new head on it. I hope you didn't do just one side on a V6.

Sorry, missed that as water in oil. Yup, dish washing fluid is a good flushing agent.

Drive it around with that soap in there and then flush it out real good with water and then replace the coolant.
