I started stripping he 2010 gas motor on my 1010c (its a replacement). I have heard that the web between cylinder bores where the deck plate mounts is susceptable to crackings, well mine has them!

. Looking at this logicly i can't see where this will ultimatly effect the engine. the actual bore is in the deck plate and the web thickness seems very thin for a crucial location. as long as the sleave bores are sound, there doesn't seem to be any way for coolant to enter . also, the seperation of oil to coolant occurs much lower in the bock. I saw no evidence of oil/ coolant or coolant/ oil contamination when draining fluids. Am i crazy to continue going forward on this project? I want a rebuild that will be machaniclaly sound and allow me to use this crawler tractor/dozer for light work around my place. Is this a necessary to repair? look for a replacement block? I have read that 99% of these motors crack in this location, so a replacement may not be easy. What do you guys think?

I believe that as long as the cracks are not far enough down to be through the area where the o-rings are, it will not be a problem.

I think that you probably don't have to do anything. I wonder if you might cause more harm by creating stress when welding them.
If the end of the crack is quite visible, you might consider stop drilling the crack if possible.
