Dodge 440-3/440 heads - RV vs.standard
It's time for my 1978 Dodge 440-3 motorhome heads to be rebuilt. The only difference I know of is the coolant passages. RV heads have a "figure 8" shape, while the standard has a circular shape. I don't want to use the heads off my RV because of several stripped header thread holes and a broken "ear" or valve cover screw hole. I pulled the heads off a same year 1-ton van that has the same casting number,"452's". Can I use these? Besides the coolant passages, are they the same? Is the different passages enough reason NOT to use them?
