Yes, they are shorter... I know by experience lol I have one as well and my truck start misfiring after I put it on it wasn't letting one of the valve open fully. Put the original one back everything back to normal. I have a 86 f150.

They will work on about any 300 except those with the bolt down rocker arms. Those are a little bigger and will hit. (It can be made to work with a big hammer though. 
)
I don't believe you'd find those in anything but an 86 though (or an EFI engine).

ok thank you !
Try for the info.
Now I'm kinda pissed...
I really wanted that v.c.
But now I know what the noise is for sure.
Thing was it was running great and I was getting on it a bit !
Thought a had a pushrod /lifter issue.
The factory one is not as cool !

Nice looking setup. 
You can put the Powered By Ford valve cover on, (had one on mine for a while), but it does take a little work. I was serious about the big hammer. About all that really happens is one of the front most rocker arms binds with one of the baffles. The older rocker arms were a little bit narrower, so the baffles were closer together. If you knock them to the side some, it'll clear that up.
Another thought is to do what people sometimes do for roller rocker arms (which are much bugger). Buy two valve covers and cut the top off of one and the bottom off of the other, and then combine/weld them together. It makes for a taller cover with more clearance.

If you really want to run it, and feel like spending some time or money, you could fabricate or have a shop fabricate a spacer. It would go between the valve cover and the cylinder head. Find a shop that has the equipment ( waterjet, laser or plasma cutting table ) . Choose either steel or aluminum plate in the thickness you need.
It will require running two gaskets and either longer bolts or studs.
Not real easy or cheap. That's why most guys just cut and weld two valve covers to gain clearance

roadrash63,
I changed the valve cover on my 1986 to a Power By Ford cover and had the same problem [loud tapping]. The baffles [previously mentioned by AbandonedBronco] where the PCV valve is located were being struck by a rocker. Since the valve cover had just been painted and I wanted to keep it looking good, the cover was removed from the engine and turned upside down on a blanket on a sturdy table. The point of baffle interference was easy to see [shiny and slight indention]. A ball shaped hammer was used to gently, but firmly move the baffle away from the point of contact. It did not take much.
Once replaced, there was no more noise and it has been in place for several years.
