- Remove the cylinder head - Disconnect manifolds, timing components, and head bolts; lift the cylinder head off the block
- Clean all mating surfaces - Thoroughly clean the cylinder head and block decks; remove all old gasket material, oil, and debris
- Check surface flatness - Inspect both surfaces for warpage using a straightedge; resurface if necessary
- Install new head gasket - Position the new gasket on the block deck with the correct orientation (usually marked "TOP" or "FRONT")
- Install cylinder head - Carefully position the cylinder head on the gasket; align with dowel pins
- Use new head bolts - If torque-to-yield (TTY) head bolts are specified, always use new bolts
- Torque in sequence - Tighten head bolts in the correct sequence and stages per manufacturer specifications
- Reassemble engine - Reinstall manifolds, timing components, and other removed parts
- Refill fluids - Fill with correct engine oil and coolant mixture (50/50 antifreeze/water)
