"Blem" heads from a top-flight manufacturer, AND it does not involve seats falling out, or faulty guides? I'm good with that. (i.e., cosmetic problems, not functional problems.)

"Blem" heads from a bottom-feeder company? Hell, no. Their "good" heads need rework, I can't imagine how bad the "Blems" are. Seats with improper press-fit are not "blemished", they're junk that needs total rework. By the time you pay to fix the seats, and the valve-job afterward, you shoulda/coulda/woulda bought decent heads from a REAL manufacturer instead of dirtbag "aluminum butchers".
