New engine has loss of compression

""the spacers under the springs. The spacers were just little shims of copper, and they weren't hardened like they should have been""

WTF ? That is the second time I've heard this , I have taken a part a few RPM heads after hearing this and have never seen the copper washers , only hardened steel cups . Y ou have pics of this ?

Is this getting to be like watches , they making fake RPM heads ?

I wish I took some pictures, but when I took them into my engine guy he took a valve out to see the seat, and as he took the spring off and saw the copper spacer he just said "thats why I'm not happy with edelbrock stuff" Then he showed me what should have been there. I take it this isn't too common?

At least when I get the heads back they can actually be bolted on...
