Edelbrock head ready to run out of the box?

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.

That is Speedmaster quality. A set of SM’a I got last year were as bad as what you’ve shown. At least Edelbrock specifically states to use adjustable rockers. Speedmaster iirc makes no mention of that, and as seen on many posts here many are using oem non-adjustable rocker arms on those just bolting down and rolling without doing something about it. Yikes
