Changing head gasket.

Changing head gasket.
Dear all,
My owners manual suggests I remove the bonnet (hood) as a first stage to removing the cylinder head. Is this absolutely necessary? Is it also necessary to remove the cams from the head also. I was planning to set everything to TDC, mark accordingly and remove the upper timing chain by unbolting the sprockets from the cams. Am I missing something here? The head gasket seems due for replacement and I don't see the need to mess about with the cams. All advice very welcome!

HI PerErs:
First off, welcome to the forum! Don't forget to introduce yourself in the intros section.
I've never done the head gasket, and undoubtedly would never try. But, I do know that the bonnet is easy to remove and if I were doing the work, I'd want the best possible access. Don't forget, the head will be very heavy.
I also hope you are planning on doing the valve seals as long as the head is off. That's standard practice.
best,
Scott
