- Remove the factory manifold with the engine at room temperature to avoid warping
- Replace the cylinder head gasket and use new bolts to prevent leaks
- Torque flange bolts in a crisscross pattern to maintain sealing face flatness
- Recheck torque after the first heat cycle to prevent joint creep
