Caution 1: These engines are difficult to work on and require special tools for many procedures. For any procedure involving timing chains, camshafts, or cylinder head removal, the steps must be read carefully, and disassembly must proceed using the special tools; otherwise, damage to the engine could result. Caution 2: The engine must be completely cool when the cylinder heads are removed. Failure to allow the engine to cool off could result in cylinder head warpage. Caution 3: The manufacturer states that the cylinder head cannot be machined in the event of warping. If the cylinder head warpage exceeds 0.001 inch (0.0254 mm), it must be replaced.

Position the new gaskets over the dowel pins on the block. Don't use sealant on the gaskets. Be sure the FRONT TOP marks are positioned correctly.

Valve components such as retainers and keepers should be checked for wear and cracks. Any questionable parts should be replaced to prevent extensive damage during engine operation.

Thoroughly remove all traces of gasket material with a gasket scraper and clean all parts with solvent. Use a rag and acetone or lacquer thinner to remove any traces of oil from the gasket mating surfaces.

Cover the lifter valley with shop rags and use a vacuum cleaner to remove any debris that falls into the cylinders.

Remove the hydraulic chain tensioner.

Apply a small dab of grease to each valve stem lock.
