AJ Stage 3 heads

I have two sets of AJ stage 3 Olds heads one set has been welded up but need to be machined, both sets of heads are dual plug heads. Do they make good power what are the pros and cons with these heads and how do they match up against Dart heads.

 

they make great power, as does anything that Alan Johnson ever laid his hands on it seems. if i remember correctly when they ran the T/AD with that combo they won the championship and alot of races. i think the car ran in the 5.70-5.80 range with a roots blower. call and talk to someone at AJPE...they are nice people to talk to.
