Has anyone ever heard of these heads??? http://www.araoengineering.com/Ford/frdsmb.htm
It sounds almost too good to be true! Granted these heads are ridiculously expensive, they may be worth it some day down the road if they can really make the numbers they say, over 400cfm at 600" lift!!!!! tell me what ya think or if ya have ever heard of anyone running these.
