RE: What heads would go best with current setup
The AFR's are the best heads available for a 5.0 in my opinion, but if your gonna be stroking it anytime in the near future go ahead and get the 185's now, just be careful of your cam selection since the bigger valves are gonna be closer to your pistons. Really the 165's are great, but with more cubes you want bigger valves.

RE: What heads would go best with current setup
People at the dyno I went to today(6-5-04) said I should go with the Edelbrock Performer RPM and theyd go great with my current setup.
They also said it'd get me a good 80+hp out of them as well, this sounds very good to my ears
and for about 500 bux less then the AFR's?
I think i might be sold!
Airflow research really that much better?

Canfield's make the best heads for the 5.0 but are very very expensive and not easy to find.
AFR makes a great head also. I've seen tests between the AFR and the Canfields and the Canfields edged them out every time. But anyway....
You're going to want a AFR 185 for a 331 or higher (351W or higher get the 205s). 165's for a 302. The problem you're running into is you're getting ahead of yourself. Getting the AFR 185s at this point would probably hinder performance but would save you money in the long run. 165s would give the best power gains at this point HOWEVER when you stroke it won't give the best gains at that point so you will be wanting a bigger head and dishing out more money. Don't get any of the GT-40 type heads. Horrible compared to others. The GT-40Ps are if you're on a budget however with that you're going to need new headers.
You have to decide what's more important to you and what goals you're going to acheive with the motor. I personally say get it stroked and new heads at the same time.
As for horsepower gains I'd say expect to see anywhere from 50-60+rwhp depending on tuning etc.
