Edelbrock head ready to run out of the box?

I just received a new set of edelbrock performer rpm cylinder heads 60779. From Summit.
I should note that there was a lot of metal machining curls in the box and in all of the passages of the heads.
I first put a strait edge on top of the valve stems. they are NOT all the same! 4 are and the other 4 are lower with the lowest .024" below.
I guess this is why edelbrock says you must have adjustable rockers.
