Thank you for the firing order. Is it possible to get more detailed information on replacing the cylinder heads, please. The info given is too vague.

You need a repair/service manual there's procedures that you have to follow its not simple

This job is not for the normal DIY mechanic as you need to remove the oil sump and many other components. Repair details are too large to be printed here and a reair manual is the best option.
