Ok now I am confused.
Yes, I just looked at the head and found the four holes for a valve cover. Which would give me options if I need to replace the cover I have that is not the square and truest looking cover.
So maybe it is a 55 bottom end, and it is a 55 head, but maybe not out of a car? Could they have been producing heads with the holes for a four bolt but installed it with a two bolt cover because it was going in a car? Or is it a replacement head, coincidentaly a 55?
I guess it matters not.
