Hey ADK-Roadrunner,
I went through the same ordeal, trying to decide if I wanted Stealths or Edelbrocks. I researched for quite some time on what was the best overall cylinder head for street use for the price. I went with the Performer RPMs. Yes, the chinese knockoff's called 'stealth heads' are cheaper, but by the time you replace parts you are nearly at the same overall price tag (also, they are around 20-30CFM off their advertised flow rates). Edelbrocks customer service is second to none, along with their warranty. We vote for products every time we click the 'buy now' icon on a website, and I could not see my hard earned dollars being placed in CHINESE goods unless absolutely necessary. I have replaced nearly EVERY 440 source product I have installed on my car, like the water pump and oil pan, because the quality was and is inferior to others I have used and I could even torque the oil pan to spec due to the inferior metal quality. I ran the E-Heads right out of the box, with factory pushrods and valvetrain with absolutely no problems. I now have switched to a solid camshaft and I am running the crane ductile iron adj. rockers and went with an off the shelf pushrod (9.25" length) and had once again, no problems. I drive the car nearly every day, just this last weekend I drove it to and from Daytona Beach which is 200 miles; getting around 12 MPG :headbang: Spend the extra money up front, buy the aluminum heads, go with around 10:1 compression vs. 9:1 with Iron, and have fun. I can't tell you how much better it looks to have aluminum heads under the hood other than old Irons.
You'll kick yourself later for spending a small fortune on Iron Heads that are comparable to Aluminum. Trust me, i've done it once and i'll never do it again..
If you go with the Edelbrocks, you'll have plenty of flow to make big power even at lower lift ranges. I would go with a .480-.525 lift camshaft, 110-112LSA, and mild duration. If you want to make good power, while on a street friendly valve train, I would check out the Comp XE275HL camshaft. It has a 2000-5800 RPM range, which would make right-off-idle power and make stump ripping torque. I had a 285' in the car, and it sounded like a radical solid lifter camshaft, but ran like a baby hydraulic. Smooth as glass with a 4-speed. My .590 solid really makes me want to switch to an Automatic sometimes, it isn't too fun in traffic...
