What's being used these day's for gluing the mod filler blocks to the blocks [ dry or cooled ]? new products? How bout the best product for a spark plug insert adhesive?

A product called PC-7 works for me. 2 part epoxy that is really easy to work with. I run wet and don`t have leaks. I would be careful about using any kind of adhesive on sparkplug inserts, mainly because it might interfere with heat transfer from the sparkplug to the block. Sparkplugs will burn up in short order if they don`t transfer heat to the block. I seen this happen when a friend used a steel Keensert to repair the threads. Plug would not last 3 laps.
