If you put to many in you get into cooling issues get a good company to sleeve the block and you will be fine. between my friends and I there are 8 of us that run golden eagle sleeves and none have ever sank or anything else. as for the block gaurd. I ran an inline pro in my block for over 2 years with no issues and the block was still good as new when I pulled it for sleeving. even with 92k miles pistons rods bearings cylinders everything was perfect.
block posting is as old as automotive racing. If you think about what it is that a post or a block guard or sleeves are doing they are only bracing against the lateral motion of the crank. which means the major and minor thrust sides of the cranks rotation. the spacing of the posts is dead center with the cylinder bores on the front and rear of the engine on the thrust sides which means that bracing anywhere other than the thrust angles i.e. crank or flywheel side of the engine is doing nothing. the void between the posts has nothing to do with any weakness its simply all that is needed nothing more. A block guard is bracing an engine in areas that isnt even in need of bracing, and in turn causing other kinds of problems. The floating deck made by Honda was done for a very good reason, and its still used in thier highest HP 4 banger today. Ive never seen posts crack...
Now you say that everything was perfect but did you run a dial bore guage in the cylinders to see how tapered they became? I guess it didnt matter since you were going to have the block sleeved, but I wouldnt recommend using a blockguard to someone who doesnt plan on spending $1000 to sleeve thier block, because after using one of those they just might have to have thier block sleeved or like one person I met had to ditch the block and start over...
