wow, was that really necessary?
Ok, so head looks like a head to me. Bent valves and all.
For starts put a towel over the head, place a large socket that fits the outer diameter of the valve retainer hat and give it a whack with a mallet. The springs will compress, the keepers pop out and the springs will fly off. The towel over it will keep the parts from putting your eye out and flying all over the shop.
You'll need a good valve spring compressor tool to reinstall the next set. I agree that the best thing for you to do is to take it to a shop and have them hot tank it, or at the minimum parts wash it, remove valves and then resurface the head, regrind the new valves and valve seats, lap them and reinstall everything nice and tidy.
You said you worked in or near a shop so maybe some people can help you with the task?
I spent $70 to have the head resurfaced and cleaned with install/reinstall of all valves (but no re-cutting) included.
