I don't get it. Why do people jump up and defend Edelbrock or 440 Source heads and say that you should expect to have to clean them up or do some work and yet in another post where people are complaining about a $75 sending unit and everyone agrees the aftermarket is to blame?

As consumers we should at least expect that a set of heads that costs from $1000 to $2000 and are promoted as bolt ons should at minimum have a proper valve job including spring heights and stem heights etc.

Allowing manufactures to send out product that has to be checked or realistically redone just enforces the behavior that they can turn out poor quality and we will continue to pay for it.

If they are turning out rough unfinished castings then sell them as such.
