What's on your "to do" list for this winter on your race car?

I have done major winter thrashes the past 4 years on my stuff. This winter, I'm intentionally not planning any major work. Just small maintenance and "fix annoying little issues" activities. I need to clean and organize my shop a little too.

I am also contemplating sending off my dual 650's to a carb builder to have them gone through and re-calibrated to my current 505. They were originally built for my 440, and when I stroked the engine, I just kinda "winged it" with the jetting, bleeds and other adjustments for the hotter 505. I'm probably in the ballpark with them, but sending them to someone and giving them all my engine and cam specs might get me that last 20% of the way quicker. OR not - I know it's sometimes a crapshoot!
