they are a basic smog head with horrible ports. if you have the time and skill you can make them work well by porting them and putting in bigger valves. otherwise ditch them. it takes enough money just putting in bigger valves to nearly justify buying better heads. after the valves your just about 30 hours of porting away from power.the afr is a real nice head.just bolt on.
Definitely agree. One other interesting good quality option is the new rousch-tweaked world heads - see them at www.worldcastings.com (http://www.worldcastings.com)
