Bump your timing back up to 12 or 14 and readjust your idle. If you trust your temp gauge that's good enough for me. You can get an IR thermometer to double check it.
Yes, check your vac advance. Make sure the weights move freely & are lubed and make sure the vac can diaphragm isn't leaking or blown out. Easy check...hook it up to manifold vacuum and the idle will jump noticeably. If it doesn't, the vac can is bad or you already had it hooked up to manifold.

Perhaps on the radiator, it looks very new and clean and it never heats up besides when it is stopped. I may have to bite the bullet and have it pressure tested. I set the timing back up, no change their in temp less it may heat up slightly faster. The vac advance should be ok as I put a new distributor on it a few months back, can test that as well though just to make sure.
