Are Speedmaster Heads Good? I've Heard a Lot of Bad Press on Edelbrock 340 Heads Lately

I have been thinking about getting some performance heads for a while. Maybe I should have bought some Edelbrock heads before the quality went downhill. I understand that since the company was sold, quality control has left the building. I have a few questions:
1. Where are Edelbrock heads made now?
2. Are the horror stories I have heard about the poor quality of their heads true?
3. I guess a lot of people here have purchased Speedmaster heads. How are they quality wise? And do they respond well to being massaged. I think I have read that @pittsburghracer has worked on them.
I have a 340 with stock iron heads that is built to about 375 HP.
