This is for the Fe guys, do y'all have rocker arm noise. When I drive the car I can hear the rockets , not sure if I'm supposed to. I have a 390 bored .030 roller cam and zero decked.

Unless you have solid lifters where you need to adjust the clearance, your valve train should be silent.

I have the same issue with a 5.0L from a 2000 Mountaineer. I swapped out the valve springs for stiffer springs and the cam for a Ford Racing 'E' cam. I did not change the lifters, push rods, or the rockers. The valve train sounds like a sewing machine.
JJ, We have almost the same set up. 01 mountaineer motor but with a b cam. went with stiffer valve springs. Does yours sound like this? Cause not sure if I have the same noise.

There shouldn't be much noise from a hydraulic setup, especially a roller lifter. My 302 is silent with hydraulic flat tappet cam and roller rockers, and the 289 with roller lifters and roller rockers is also silent. The rockers should be 1/2 to 3/4 turn past 0 lash. This places the lifter plunger about .030" below the snap ring.
If you also have roller rockers ala Harland Sharpe etc they are not silent. If not and this is a recently built motor there will be some valve train noise initially that will quiet down once it has been run in. It would also be a good idea to go back and re-set lifter preload. I prefer doing this hot with the engine running, but can be messy if you're not well prepared.

REFRAIN from revving during valve adjustment while running. It amazed my how much and how far the splashes went. it was one of those, "well that was a stupid thing to do" moments.
A old trick is to take an old steel rocker cover and cut the top open just enough to expose the adjusting nuts. That will help keep the oil where it needs to be and not on the ceiling.

Old school guys that have worked on 260-289-302-351-400's will have a set of the wire plugs that slip over the oil hole in the rocker to eliminate the "splash". Easy-Peasy when you have the right tool(s) for the job.
Just sayin' . . .
