What happens when a cylinder head gasket fails?

Step 1: Inspect the engine block and cylinder head.
What should I remove to install a head gasket?

What happens when you remove the cylinder head?
Removing the head is a major step in removing the cylinder head. These head bolts hold the cylinder head to the engine block. The head bolts are long bolts that go through the cylinder head and head gasket and when torqued properly create a seal between all 3 components.
Where is the head gasket on a V-8 engine?
The head gasket is found between the engine block and the cylinder head or heads in a V-type engine.
