Valve Cover Removal on 1992 Chevrolet S10

This is the origional gasket, How do I get the valve cover off, I have removed the bolts, undid the wires, and lines. There is a bracket at the back supporting a hard line, with part of the wiring harness passing between the valve cover and the hard line. (passenger side). How do I get the cover to come off.
