stealth heads vs edelbrock heads

I purchased a set of CNC Stealths back in June or July. I had heard on FABO from a few people that the valves that come in them are OK but the rest of the hardware was risky, and should be upgraded. What I did was talk to Kim at 440 Source and also called Comp Cams first before ordering anything. I wound up choosing the cam I wanted from Comp and arrainged to have Comp ship the matching valve springs and hardware directly to 440 Source and they assembled them with the Comp parts and then shipped the heads to me. I have not installed the heads yet, but I did unpack them and inspect them as close as possible without disassembling them. I don't see any problems and I'll say the casting quality looks real nice. 440 Source ads claim that the CNC job opens the intakes up to 255 cc and that they flow 330 cfm @.700. I don't remember if they list any low lift numbers. I choose the Stealths over the Edelbrocks mainly because of the stock appearance/total lack of and logo of the Stealths. I'm going to paint them Chrysler orange along with the motor for the stock look. I'll be posting complete results with the car once its up and running and I make some passes at the track.
