Hey Glort, your probably right, scrap the engine and sell on the Dunlite head.
The best value in generators always come out of hospitals and etc where they have been back up to critical systems. Monthly maintenance and no work, a lot of them even have heating systems built in so the oil and etc are at working temperature the moment they kick in.
The only worry is that the bores may have a bit of glazing due to low load testing, easily cured by a long run under heavy load.
