I am changing the timing chain on my 2004 5.4. w 180k
Does anybody recommend any particular brand for the parts?
What else beyond the phasers and the guides should I change out whilst it's opened up?

 

I would just use ford for all the parts. Silver state Ford parts was the lowest price for me and had everything.

That said I would go with the older cast iron tensioners from the 98-03 5.4 2v motors. They have a ratchet mechanism that doesn't let the tensioner sag back to completely slack if the engine sits a while it only says back about an eighth of an inch or so

I ordered a melling high volume oil pump as well. I am on the fence as to whether or not I should install it as my oil pressure is not terrible at idle, but while the chains are off would be the time to install it...

 

I recently did the whole nine on mine.

I used Ford phasers and bolts and used the Melling with the plastic tensioners kit from Rock Auto all the new parts looked exactly the same the Melling parts even had Ford part numbers on them.

The price difference mostly paid for the rockers and lash adjusters I got from Jegs

I also replaced the oil pump with the Melling high volume pump
