About 2 weeks ago, I put the head on my motor and sealed it up with a nice coat of gasket sealer. I had everything back together and ready for paint when I noticed the pinging sound of sticking valves. I decided to go ahead and paint and figure the rest out later. A few days ago someone else posted about the same pinging sound I was hearing and it turns out that it could be bent valves since I forgot to loosen or remove the tappet adjuster bolts when installing the valve cover, DOH! So now I have to remove the head to figure out which valves are bent and replace them. Problem is, the combination of gasket sealer and high temp paint along with 2 weeks of drying time have now formed the equivalent of cement. That head is stuck tighter than (insert dirty comment here). I took all of the nuts and bolts out but I can't get the damn thing to budge off the cylinders. I'm afraid to pry too much because I don't want to end up busting fins. That's why I replaced the head to begin with, well that and a leaky head gasket. So I'm open to suggestions on how to get this thing free, preferably saving the new head gasket if possible. Someone else, I'm sure, has made the same dumbass mistake and had to remove a fresh head. How did you do it?
