You should be fine, I had to replace one and left the other. All new rollers on both banks and it runs fantastic and very quiet (at least as quiet as a 5.4 can be)

If existing cam caps are in good condition, you can replace the cams. Replacing lash adjusters and roller rockers doesn't require installing new cams.

I installed the Ford Racing M-6529-3V lash/rocker kit when I did my timing job. Updated design that allows better oiling (larger oiling holes), lower friction on the lash adjusters, rockers are lighter and stiffer. Originally for the Mustang engine.

I believe these contribute to the quieter engine operation.

You have an 04!!!!! Be sure to get the correct adjusters as the are different. 05+ I think uses the same but the 04 is 100% different. I found the best prices for the adjusters and rollers from fordpartsgiant.com

Also, I re-used my cams and cam caps but replaced all the adjusters, rollers, etc... while doing my timing job.

But all cam caps are supposed to go back exactly how they came out. I really wonder about the cam caps if you put new cams in . I think a really experienced hand may know . I would talk to a reallly good machine shop as this is really important . Let us know what you find out . It is a hole in my data base . I suppose it may depend on the condition of caps ??? I always thought they were fitted to that cam .
Yes I would want the new rollers that have oil hole pointed at roller , my lashs were the improved ones but I didn't khow about new type rollers then if available . Lashs are very flaky/ subjective to test .
Best to repalce them all . Mine had thrown one intake roller to the side but missed the cam . So I replaced all rollers and lashs . But I chose to put cams back with all rollers installed at the timing point with lobes(cyl 1 and 5) pointed per ford book at timing point then put chains on . Very carefully sneaking up to final torque in sequence per ford . That $$$ valve tool sucks .
Keep us posted

As the cams and caps wear together (which is why they must be re-installed exactly where they came from) with the caps liable to exhibit more wear (aluminum softer than steel), I certainly wouldn't reuse them if installing new cams. That being said, you'd get to a point where the heads' towers may be more worn than the cams, requiring replacement of the heads. Unless the cams were really damaged (more than visual wear, and even more than subtle finger-nail catching), I'd be inclined to leave everything as-is, replacing just the adjusters and followers. Best to cross that bridge when you get there; take it apart and assess what you have. With higher mileage, there will be some wear present and to be expected. Mine exhibited visual scoring but could barely catch a thumbnail, so I made sure to re-installed the cams and caps exactly how they came off, and I'm not going to worry about it with how smooth and quiet it now is. All my followers and adjusters were perfectly fine upon inspection but were replaced anyway, simply because I was in there, and are both smaller with more moving parts than a simple camshaft. New cams would also require a specific break-in procedure, which can result in disaster if not done correctly.

The followers have a re-angled oil orifice, and with a smaller hole than the originals ('04 at least) did, as this both better directs oil flow AND increases oil pressure, so I certainly wouldn't go backwards to a larger orifice again.
