valve cover

I'm trying to remove the valve covers to change the gaskets since it is leaking oil and do valve adjustments, but they won't budge. I've removed all the required nuts and bolts.

Hello, Not sure what the proper name of it is, but I'm looking for the rear valve cover (closest to the rear of the car); or maybe the set if no one has just that for sale. Please let me know. Thank you! 571-316-4951
