1. Lay a clean shop rag in the tappet valley to catch any
gasket particles. Clean the cylinder head, intake manifold
and the cylinder head-to-block gasket surfaces. After
scraping, lift the cloth so no gasket material falls into the
holes. Check the cylinder head and the cylinder block
gasket surfaces for flatness. (Refer to page 62-36.)
Caution
Gouges in aluminum components will cause gas-
kets to leak.
