Update: I just split several of these oak blocks and checked them with a MM ("General" brand from Lowes) and a small minority of lighter blocks had a moisture content just under 20%. The majority are in the mid 20s with several of the heaviest blocks at 26-28%. Just to test them out, I threw several random blocks in the Fireview on a large bed of hot coals (I'm burning a mix of kiln dried oak ends and 1 1/2 year seasoned Ash) with a stove top temp of 400. Man, did they ever light up and heat up nice! In 30-40 minutes stove top temp was at 600. I'm running out of the seasoned ash, and the four cords of mixed cherry, maple, ash and locust I managed to C/S/S this summer is averaging low to mid 20s on the MM. If oak with MC in the mid 20s burns this nice and hot, I can't wait to have some seasoned oak in the stacks. Anything wrong with standing these up around the stove to dry a bit if I rotate them and don't leave them there too long? Anything wrong with burning any of this now, given an average MC of low to mid 20s?
