Install the bolts (long bolts inside, short bolts outside) and tighten them finger tight, then follow the recommended sequence and torque specifications.

Place a wood block against the end and strike the wood block with a hammer.

On all engines, lubricate and install the valves, then install new seals on each of the valve guides. Using a hammer and deep socket, gently tap each seal into place until it's seated on the guide. On V6 models, use a hammer and a seal installer to drive the seal onto the valve guide/head casting boss, ensuring the valve spring seat is in place first. Don't twist or cock the seals during installation or they will not seat properly on the valve stems.

The valve covers, intake manifold, exhaust manifolds, and timing chain cover must be removed.

Make sure to drain the residual fuel from the cylinder head and oil from the high-pressure oil system before removing the fuel injectors. Failure to do so could allow fuel or oil to drain into the combustion chambers, onto the pistons, past the rings, down the cylinder walls, and into the crankcase. It could also cause a piston to "hydraulic" when the engine is started, potentially damaging the piston or bending the connecting rod.

Most machine shops will not have a core set of heads unless the vehicle has been on the market for close to five years, meaning you may have to wait for the rebuilding work to be completed on your heads.

Perform all inspection procedures and make a list of the items that need attention.

Remove the valve covers.

Ensure the new gaskets are installed on the correct cylinder banks, as they are different and cannot be interchanged. Position the gaskets over the alignment dowels in the engine block.

These procedures should be performed by a qualified automotive machine shop.
