Mind you the pistons may not be the stuck culprets as it could be the valve train.

I agree , more times than not it will be a stuck closed valve. If you can turn the engine backwards even a little it is probably a stuck valve . A good way to make this test is to remove the starter and use a cheater bar on the teeth of the flywheel. remember , the engine turns clockwise when it runs . you want to see if the engine will turn just a little in the counter clockwise direction . I wouldn't remove the head unless it was the VERY last resort . Seeing the tops of the pistons really doesn't tell you much of anything . If it turns out to be a stuck valve , I would remove the manifolds and valve cover. Its pretty easy to spray aerosol sili kroil through the ports to the valve stems . In worse cases I have used vice grips on the lower mushroom end of the valve stem and work it back and fourth while oiling.
