Is the following ENGINEERING/PARTS ILL showing the hold down grommet position correct?

It appears to show the grommet installed from the underside, which would be incorrect. It wouldn't seal in that position.

THANX! for that.
Been so long I let FORD fool me.
How can they release an ENGINEERING/PARTS ILL and no one has caught it?

That explains where that comes from. A lot of people have told me that over the years. When I put on some aluminum covers I tried it. I put a jam nut under the washer set to the height to allow solid contact with the washers. It actually didn't work badly but it took a lot of trial and error to get the valve cover gaskets and hold down at enough pressure to seal. Went back to putting the rubber washers on top.

Likely all the drawings were done long before any parts were being produced/assembled (?). BTW: They also drew the T-Bird’s Rt. ex. manifold heat valve upside down.

I think because this is a parts illustration rather then a shop manual picture they were trying to show that the valve cover gasket and the two grommets are supplied together. They probably could have done it a little better. The parts person only has to get you the right parts, he doesn't care how you put it together

I did the same as Moonshadow when I first put the engine together because I saw the diagram. Ran into the same problems. I got everything so no leaks, but it was a pain to pull and install the covers so I eventually changed them

If you look at the 6549 ADJ SCREWS, it shows early and late (mid-1956/ ). So the ILL has to be at least mid-1956 production. FORD PARTS DIVISION used modified ENGINEERING DRAWINGS (as well as SERVICE DIVISION for SHOP MANUALS).
How was this released with no one catching it?

I don't know how it worked in parts departments but the shop manuals have a lot of errors and when caught and other service changes happened they put out REVISIONS to correct it. Unfortunately only dealers got the revisions and a person like myself with no connection to a dealer never get them.

Correct. Service Manuals were printed on the quarter year, corrections included. Same with PARTS MANUALS, upgrades every quarter. Corrected service procedures were also released with SERVICE BULLETINS.
But another poster showed a page from his 54 SHOP MANUAL (don't know if FORD or MERC) that showed the correct sequence.
It may be the ILL is first print and the later 56/ rocker arm adjusting screw ILL inserted on that particular ILL.
BASIC PN 6A506 is the BPN for a valve cover set incl grommets. The grommet is also available separately.
Never say never regarding FOMOCO.
