Installation Notes

Professional engine builder or mechanic installation is strongly recommended.

Ensure engine is cool - Allow the engine to cool completely before disassembly
Disconnect battery - Always disconnect the negative terminal before working
Drain coolant and oil - Drain the cooling system and engine oil to prevent spills
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)
Bleed cooling system - Start engine and bleed air from the cooling system per manufacturer procedure
Check for leaks - Inspect for oil or coolant leaks around the cylinder head area
Road test - Test drive to verify proper engine operation and no overheating
