cost to rebuild cylinder head
The cylinder head must be removed, and the thermostat and its gasket are often replaced as part of the repair. In addition, the cylinder head may need to be machined or replaced to repair any cracking or warping. Many shops will also flush the coolant and replace it as well, which can cost about $50-$150. Many shops will include this in the repair cost. Purchased separately, a cylinder-head gasket can cost $5-$500.
