I was looking at a set of heads off a 1992 mercury marquis first year of the 4.6L heads the intake runners are bigger than the 99 up heads other than that the rest of the head is the same as the 99 up. I was wonder if anybody has the flow #'s off these heads??? I have a 2001 gt it looks as if they may flow more on the intake side stock than the 01 heads i might swap heads and put my cams springs and valves on it with a 5 angle vavle job.

does anyone have anything on these heads ??
