I am thinking about buying a set of aluminum heads, but I just not sure which ones. Like Dart Pro1's or Edelbrock Victor Jrs, or anything else I can afford. So does anyone have a preference or dislike about either of these heads?

Sorry, they are for SBC 406.

Chevy's "fast burn" heads are really good. At $1100, it's not a bad price either. Check www.goodwrench.com (http://www.goodwrench.com) or www.sdpc.com. (http://www.sdpc.com.) Accepts both valve cover styles, has provisions for wire looms to bolt to head, raised port design on intake ports, 2.00I and 1.55E valves, and more. GM compared them to several other heads. A comparison is available on the above web sites.

Go with the Air Flow Research heads. Not sure you can do better for the money.
Talk to Shawn Peterson; he just did the research and bought a set for his 406.

I went with the Victor Jr's. I was ready to order the 210cc AFR's but my machinist talked me into the Edelbrock's. The biggest difference he see's are that the Edelbrock's flow what they say and the AFR's may or may not (not as consistent). I looked at the flow chart from AFR on the 210's versus other heads, including the Victor Jr's. They were only a couple of numbers different on intake/exhaust flow. The Edelbrock's need blending at the ports and bowl work (at least the bare heads do). I will have about $1500. in the heads with bowl and port work, valves, roller springs, titanium retainers, etc. That's about the same price as the stock AFR 210's. They should out-flow them but who knows. We're shooting for 600 h.p. without nitrous.
The bottom line is that you can't go wrong with either head. AFR builds an EXCELLENT head; I feel I ended up with a better flowing head for the same money but that's debateable.
