I don't hate Stealth heads. I have used close to ten sets of them and for the price they are hard to beat. But to tell that they are the best stock OTB replacement heads is false; they are not. Although not perfect, the Edelbrocks and the mopar performance heads are better material and better quality overall.
Here is a "383" I built some two years ago with Stealth heads, mild hydraulic cam and 460+ hp
