In this case, amount of disassembly and measuring is really minimal, probably 3-hrs. As is rebuild, perhaps 5-15hrs.
Compared to 10x more work and cost of milling and machining that other destroyed engine.
Yes, I've replaced blown-headgaskets in the parking-lot of Willow Springs. But if I had it at home, I'd spend a little more effort and just replace all worn or half-worn components while I'm in there.
