Like I said- the deck heights are different on the B17A and B18A. Therefore, in order to use a B17A crank in a B18A/B block, you would have to have rods custom built to the correct length. He cannot possibly have OEM rods on that setup. It simply isn't possible. What you could do, however, is run a B17A crank with B18A spec rods in a B18C block- the numbers match up perfectly- and have an incredible rod ratio.

By resizing the cylinder walls, do you mean they're bored out? If so, that would mean he's also running aftermarket pistons. In addition, this would create more displacement.

What do you mean the head has been decked? Do you mean it has been milled? If so, this is usually done to increase compression, not support RPMs.

Any way you cut it, it's still not even close to being an LS/VTEC, by definition. The point is to get more displacement by using the LS bottom end, but your friend has actually done the opposite. Actually, I think his setup is better- very close to what I want to do. I want a B16A with B17A crank and rods, bored to 85-86mm. So I'm not knocking your friend'd setup- on the contrary- I'm just saying it's not an LS/VTEC, and using it to argue in favor of their reliability is a far cry from reality.
