Are top and bottom plates required for a furring strip wall

framing

I'm going to be framing out a wall in my basement by using 2×2 furring strips, attaching them with Tapcon screws to the masonry block so that I can hang the drywall onto and also give me a little room for foam insulation.

I can't use 2×4 because it would run into my vents and I don't want to add repositioning the vents to this project.

Since I’m just framing this to hang a few sheets of drywall, can I get away without having to use a top and bottom plate or is that asking for drywall cracks down the road?

Put the furring strips on the top and bottom so you have something to nail the drywall to otherwise it is going to warp. It cannot span 4 feet with no support.
