Ross, I would port match a RPM, and remove all lettering off the manifold so that it looks like the ford intake. The Streetmaster is short at 5.875", RPM 6.0", PI 6.375" at rear pads. The CJ iron is 6.0" so, you have a choice. The BT is tallest of the dual planes 6.750". I have removed the lettering on several intakes, and hit the area with a sand blaster, then painted to look stock. It becomes difficult to really tell the difference if you want it to look period corrrect. Joe-JDC.
