Yup, I forgot to add another "zero". But as explained in the text, he has .0035 taper/bellmouth, which is about half of what I've considered to be the "worst acceptable" amount of .007.
It appears that the cylinder walls are wavy--worn in the middle, worn at the tops, less worn in between, and at the bottoms. None of that wear is good.
$400 to bore eight cylinders is $50 per hole, and my expectation is that the shop will not be using a torque plate when honing the fresh-bored cylinders. Fukkin' outrageous in the USA...but I don't know about Sweden. Have you considered showing up at the machine shop with a liter of Akvavit and seeing if they'll treat you better?
Were there any signs of cylinder head problems? How many miles are on them? $400 to "check and level" the heads may or may not be fukkin' outrageous. I assume this means they'll disassemble and inspect the valves, valve guides, valve seats, springs and retainers, and plane the gasket surface(s). Then--assuming the parts are OK, reassemble with fresh valve stem seals. I think you should be prepared for the inevitable valve face and seat reconditioning, along with bronze liners in the guides. I suppose this will cost extra. Consider having them vacuum-test the valve face/valve seat sealing after removing the valve springs and inspecting for guide wear. Hopefully you can get by without reconditioning the heads beyond installing fresh valve stem seals.
