Do I have to take both sides off?

I have a 2nd gen Dodge ram v10, and I am diving into the engine to replace the head gaskets.

My question, when I pulled the spark plugs, the right side of the engine had wet plugs, while the right had the normal carbon buildup expected from used plugs, should I take apart the left and take that to the machine shop as well with the right cylinder head, or do i leave it alone?

sorry i meant, the right had wet plugs, and the left side was dry

All that work I'd do both sides to make it last
