New Edy heads, poor quality control what to do

I sure see a lot of complaints on here about these heads.
I would not buy or pay my hard won money on a defective
or inferior product.
Buy or build what you want.
The weight savings you are looking for will not
offset the headaches of an inferior product.
On a street car, why would you ever consider running
a product that is not ultra dependable.
If your heads have core shift, its probable that there are other problems
like thin walls near torque/load/water bearing surfaces.
You probably would not consider a core shifted block as a
foundation for your build, why mess with the same in a head.
