Ok does anybody know if the flange on a set of 2.9 headers is the same as for the 4.0. Reason I ask is that I have a pair of 2.9 headers and I am in the process of doing a 4.0 swap on my BII. Not really worried about the rest of the headers just the flange that bolts to the head, i can bend up and weld new primary tubes that will work if need be. they look to be really close to the same spacing and bolt pattern from what I can see. And yes I am cheap! I don't have the money to spend on new 4.0 headers, trying to get by with what I have.
