Harland Sharp. They're a little pricey, but if you want reliability, you'll get it.

Harland Sharp #5016 or 5017 is the best fit for the Edelbrocks.

x3, do a search on poly locks for the shorter set.

I did a search and it says the 5016 or 5017 is for Bulldog heads and 5003 is for Edelbrocks. Is there a difference?

The p/n for Bulldogs is the best fit for the Edelbrocks. Several top engine builders have confirmed they produce better geometry than the 5003.

Yes the 5016 or 5017's are the best fit. The rocker is about .050 longer on the valve side to better accommodate the taller valve heights on the Edelbrock heads.
However the Scorpion Ford Windsor rockers work fine as well.

I also used 5016 on my RR heads.

One more question, will these rockers fit under the stock valve covers?

The rockers fit fine, it is the poly locks that are the problem. You should get taller valve covers. there are spacers to use with stock covers or I have in the past use the thick gaskets and doubled them.
