To embark on an engine overhaul, the first step is to prepare the cylinder heads and valve train parts by cleaning and inspecting them. Take off any old gasket material and sealing compound from the surfaces. Use a solvent, dry it, and clean all parts thoroughly. The crack inspection process of the cylinder head starts with a visual check for cracks or other signs of damage. Check for warpage with a straight edge. Examine the valve seats as well as measure valve stem-to-guide clearance. Inspect valves for wear and imperfections. Check valve margin width. Look at the valve springs for wear and take free lengths measurements. Confirm retainers' condition along with their keepers'. Inspect rocker arm components for wear. Assess pushrods as well as rocker arm studs for damage. Replace any parts that have either worn out or are damaged in any way in this section.

Position the new gasket(s) over the alignment dowels in the block.
