need some help i have a 2004 jeep grand cherokee with 4.7l high tech. I want to buy a set of heads out of a 2007dodge ram pick up/v8 magnum motor. will they bolt right up. the picture shows a cannisture on the passenger side head, i dont see this cannister on my cylinder heads. will they work? need help

 

By "high tech" are you meaning "High Output" because if it's the HO, the heads are different from a standard 4.7...
