As the title states, I'm curious to know if anyone knows? I have access to a mint cylinder head for way cheaper than I care to post here but I need to find out if everything is the same as the one on my '03. If so, I'm gonna ****** that thing up and start up grading it.

 

It'll fit. I was gunna put a 06 head on my 03 until plans changed

 

It will fit but you must use injectors from the 03

 

Glad to know. Was gonna swap my injectors into it and possibly port it and add some heavier springs. Thanks guys.

 

06 is a much better head, the valve seats won't fall out as bad as the 03-04 trucks did. You will have to use the old rocker box and valve cover, injector wiring harness, and injectors.
