How do you change a head gasket on a 1987 Honda CRX?

To change the head gasket on a 1987 Honda CRX, start by disconnecting the battery and draining the coolant and oil. Remove the intake and exhaust manifolds, along with any necessary components like the timing belt and valve cover. Once the cylinder head is accessible, unbolt it and carefully lift it off, replacing the old gasket with a new one. Reassemble by reversing the disassembly steps, ensuring all bolts are torqued to the manufacturer's specifications.
