The only good thing about that is that when using a cosworth race piston its usually a little more skirt clearance needed so if it was a good old block and managed to get honed out to like 4 thou for example that would be about perfect for those pistons..
Before i put 500 hp through it id just have skirt clearance checked..,a bit of a ball ache but no real expense and piece of mind
