You can't use Plymouth poly flanges on a Dodge poly. Gary at Quality Engineered Components (Wayfarer on here) has made up a bunch of header flanges for the 315-325 poly motors. I don't know if he has any more left over, but you should give him a call. Of course, you would need to make up custom headers with them, but at least it gives you a starting point as most shops won't even start without having the flange on hand.
