Did you get the cooling system sufficiently cleaned out in the first place. It takes a lot to remove all oil residue. I generally have to remove the thermostat and flush the system repeatedly using dish washing liquid and water. It's also possible that they didn't repair the head properly.

I paid $550 for the head to be done so I would have hoped it was done properly. The oil is getting worse is there any way it could get in to the water through the font timing cover?

How would I check if it is the head as the whole job cost over $1300 and I do not have the money to do again

You could try pressure testing the cooling system to see if it holds pressure but that's not completely reliable. It's basically just a process of elimination.

Back at the shop that did the work and see if they stand behind their work.
