I gotta agree with Earl on this.I wouldn't use anything out of the box 
these days.Eddys are known for having guide issues.

Yes, the Stealth heads are Chinese.Basically an Eddy head with a 
different look to them.Modern Cylinder Head runs their CNC Edelborck 
program on Stealth heads,that's how identical they are.And, like the 
Eddys they'll flow 320+ cfm@.600" when ported.Out of the box they seem 
to be near 260 cfm-comparable to a well ported 906,452, etc.I'd still 
have a competent shop go through them,but they appear to be well worth 
the money esp if you like the stock look.Rumor has it that the price of 
the next container of them will go up by $200-300 pr.So, if your on the 
fence I'd grab some.
