This would be my first thought as well. Put a piece of clay on the bottom of the screen about the size of a ballpoint pen and about an inch long. With no oil in the pan, lift the pan into place against the block, then pull it off and check the clay. About 3/8" to 1/2" off the bottom of the pan would be a good position for the screen.
