They are not adjustable. If you spent a lot of money on the heads and have pushrod guide plates with threaded rocker studs, aftermarket rocker arms, etc. then you can adjust them. If you had a straight up rebuild, then they are not adjustable. If they did not do the machine work correctly on the valves and the heads, then yes you could have a problem with the adjustment, but there is no adjustment, they have to get it right when they rebuild the heads.
So if your heads are stock with a stock rebuild, and they guy that rebuilt the engine is saying you need to adjust them, then they are giving you the run around.

yep...I just went round and round with someone on the 385 forum about this.
Stock studs....torque them to spec. Could also be that they are not getting proper oil supply to either the lifters or rocker arms.

Here's the page out of the Ford Shop Manual. If it was a stock rebuild, and it is the guy who rebuilt it telling you they need to be adjusted, take this to him and ask why he didn't follow the manual

Hello I come a little late but I am bothered with my setting I followed your procedure but when I serve the bolt that holds the rocker the valve goes down and does not close despite a minimum tightening. I’m talking about, of course, an unregulated rocker, as you mentioned. Can you help me please maybe it is necessary to make the adjustment with hot oil because currently cold oil the pusher does not fall down but the valve opens thank you in advance

[QUOTE=Franklin2;20575844]Ces bascules ne sont pas réglables. Ils ne sont pas réglables. Ils ne sont pas réglables. La seule façon de les régler est d'utiliser des poussoirs plus longs ou plus courts. Ou ils ont été convertis et ne sont pas en stock. Les culbuteurs d'origine ne sont pas réglables.[/QUOTE

Why did you need to touch them?
And if you can adjust them by turning the nut the valve train is not stock.
In that case only 2 ways I know how to adjust.
Find TDC of cyl #1 and back off the nuts till you can turn the push rod with your fingers then tighten nut till it just stops turning then go 1/4 to 1/2 turn more.
Then bring up the next hole in the firing order and do the same. Keep going till all 8 holes are done.
The other way and it is messy is to make sure oil level is full and motor up to temp.
Remove valve cover and start motor and let idle. back off the nut till it makes noise then tighten till it just stops then go 1/4 to 1/2 turn more doing all the same.
Messy because oil will spray all over the place and if it gets on the hot exh manifold will smoke and could catch fire so have something that could put a oil fire out handy.

If he has the stock valvetrain for 1979 or later 351w, the rockers have bolts not nuts. You have to tighten the bolt all the way down to spec or it will work loose.
If he has the earlier rail rockers, then he has studs. They do make a kit for those, with a tall nut and a allen screw to lock the nut once it's in position. Like the bolts, if it's stock you have to tighten the nut all the way down or it will work loose. Unless you get a aftermarket kit with the locking allen and tall nut.
