...that the "places of combustion" will be closer to each other generating more heat. This is different from when the bores are not next to each other -- they are then simply that much closer to water. Sorry, sometimes I get into "engineer speak."
The least troublesome symptom of thin walls is the inability to keep the temperature regulated (i.e., overheating). This can be localized, which is worse 'cuz you don't necessarily know that it is happening. Oil splash can help, but likely not. The other effects of thin walls are the inability of the rings to seal (bore distortion) and catastrophic wall failure (the dam* thing breaks!).
They do sleeve even racing blocks. If the sleeve is properly installed, it will be reliable. But if it were me, I would hold out for a different block because of the variables it introduces.
In my humble opinion, if they would have sonic checked it first, they would have seen the core shift. However, keep in mind that even with an offset bore, the rear of #2 cylinder would still be at the bare minimum wall thickness as it came from the factory (from Ford, that block was .122, .101, .108). Between cylinders, I would really like to see .140 as the lower limit. One can stretch that limit on the inside walls, the front wall of #1/5 and back walls of #4/8., but .100 would be the absolute minimum and only for less than 25% of the circumfrence. If you are trying to make some HP(500+), .150+ is required.
Cheers,
