THIS. If you're spending the money on a high hp build, it's almost irresponsible to not spend $1k more to just sleeve it. Aside from the rigidity to the block, there are other benefits. The plasma coating for cylinder bores is razor thin and it only takes the smallest conflict between piston/ring and cylinder wall to compromise it. Several tear down videos I've seen involve either sleeving it or tossing it because the plasma coating isn't something available.I have a TKM block with Darton sleeves. Sleeving only added $750 when I built mine a couple years ago. I'm sure like everything it's more now but I thought it was a no-brainer.
Over design, under utilize. Especially if you're going to "abuse" the car with track use, (extended sessions) or long highway rips back to back, etc.
All these rules of thumb are usually developed by drag car/trailer queen use and dyno rips and pulls. It's a lot harder on a motor to max it out repeatedly under full heat than it is to do a burnout and a 10 second pass.
The newer block architecture is better, but if you're gonna drop $12k-$15k on a motor, what's another $1k while you're in there?
