6. Remove the cylinder head.

* Use a razor blade gasket scraper to clean the cylinder head and cylinder block gasket surfaces. Do not scratch or gouge either surface.

Important: DO NOT use any other method or technique to clean these gasket surfaces.

* Use a NEW razor blade on the cylinder head and a NEW blade on the cylinder block.

Important: Be careful not to gouge or scratch the gasket surfaces. DO NOT gouge or scrape the combustion chamber surfaces. The feel of the gasket surface is important, not the appearance.
