When me and my buddies were in high school, the first thing that went on cars we got if they had it was all the A/C stuff. In the ditch it went. Lookin back thirty plus years ago, I don't see how we did it. I never had air on anything I had back then....and all of um had headers. If I'm able to finish my Coronet, it will be without air, but I don't plan to drive it a lot.
