I have this Edmund 6 Cylinder aluminum head and intake. I thought it was a Hudson. I have been looking at some head gaskets and what I have found don't match. The closest bolt pattern for the head off a picture of a gasket is Dodge. But the intake has square ports and the Dodge has round ports on the intake. I believe these are a set.
The intake manifold looks like Hudson to me. Is there any sort of I.D. on the underside of it? Many Edmunds intakes had some sort of identification there.
I looked all over the intake for a number but did not see one. I'm going to clean it up better and see if I can find one.
google finds a few pics from ebay of Hudson heads, they have that distinctive rectangular coolant bypass hole in front of the thermostat, just like yours.
I just did some more searching and came up with this Ebay auction. It looks right. http://www.ebay.com/itm/48-49-50-HU...r_Truck_Parts_Accessories&hash=item1c2bfb5605
Here you go Sid. Looks like it fits a 308 Hudson Hornet. http://www.classiccar.com/forum/discussion/119624/edmunds-head/p1
Definitely Hudson. Just a Note , the Hudson forum at Classic cars .com is shutting down this week. There be a public forum for Hudsons at the HET site.
