Head Gasket... Do I need the cam locking tool?

I believe I have VVT in this 2004 XC70.

Do I need the cam locking tool to replace a head gasket?

Anytime you are pulling the timing belt it is good insurance to lock the cams. If a I recall right they aren’t too expensive of a tool.

If you have to ask, then yes.

With my limited knowledge, I would have to ask on any Volvo. I know very little about which models require it which is why I posted the question.

Perhaps a better question, is when/when not is the tool a requirement?

For what it's worth, I do not believe I will be pulling the VVT hubs/pulleys. Only the cams out of their journals.

Vvt alignment is for when you've finished the repairs. Once you take the cams out you absolutely need the tool or A tool. Some people can and do make them at home.

How about the cam cover tool? You need that one as well, they are all part of the kit.

One bit of advice from experience - DO NOT crank the bolts of the tool down into the camshafts - snug is fine. You only need the big teeth to engage with the slots in the cams. The bolts are only 7mm and made of cheap steel, and I sheared one off INSIDE the camshaft. It became an ordeal to fix.

You can leave the hubs on the cams and then slide the seals from the rear of the cams to their position on the front of the engine. It’s not a textbook procedure but it works.
