Is there anybody out there who is considering buying a new Chinese cast L134 engine block ?

Metalshaper is the guy who knows his vintage jeeps.
I read a report on these Chinese blocks , the valve guide bores are out of alignment, the bores are not perpendicular to the camshaft, that would explain why the valve stems and guides are very worn after only 3k miles of use. .
