ok im new here...i have a 99 cobra and broke a rod. Decided to put another dohc 4.6 found one out of a 97 cobra. got the motor in and found out after all that my intake is different and wont work with the 97 heads. Should i ..A. swap my 99 heads over to the 97 block? B. change wiring harness and use 97 intake and stuff...or any other ideas?....
