If the measurements vary by more than a few thousandths of an inch, the block is probably warped. Another way to tell if a block is warped is to check for uneven wear on the cylinder walls. If the wear is not even, it is likely that the block is warped.
How do you test a cylinder?
A cylinder can be tested in a number of ways depending on what information is required. A basic test would involve measuring the diameter and height of the cylinder and calculating the volume. This could be done with a simple ruler or caliper.

How do you deck a cylinder head?
There are many ways to deck a cylinder head, but the most common method is to use a machine called a head planer. This machine uses a rotating cutting tool to remove material from the top of the head, creating a smooth, flat surface.
What are the signs of a cracked engine block?
The most common sign of a cracked engine block is a sudden loss of coolant. This can happen without any warning, and can result in the engine overheating very quickly.
