I am restoring a 78 Ford F150 I bought from a guy that cant tell me much other than he put a rebuilt 460 out of a thunderbird in it and I am trying to order some headers and I want them to fit!!!! under the motor I found DIVE -6015 does anybody know the year this might be and have advice on the best headers to go with for horsepower and fuel economy also I want to due a dual exhuast It has no cat exhuast in it the guy ran stright from the manifold to a motor home muffler on it it is not dual.....

Thanks for your help

 

Any 429/460 header will fit. The best headers out there in my opinion for this swap are the L+L headers. They have extremely thick flanges and won't allow warping for gasket leaks.

 

Thanks for your imput
