Fellas, I don't know squat about early GMC heads but I just came across what appears to be an early nos GMC head in the box that is advertised on ebay as an inline chevy head but is described in the body of the ad as a head for a 228, 248 270 GMC head. It is not a chevy head and to the extent I recognize anything, the combustion chamber is not a chevy chamber so it may very well be a nos GMC head. Just thought I would pass it along.
