I seen these head a while ago like everyone else. Hughes at first really bad mouthed them. After further investigation they sort of took their words back. I am pretty, sure and Bobby can tell you the straight facts, that you could still run a pretty big cam by changing the valves to the 11/32 like he is for me. My cam is .624 lift and Bobby is leaving .080 room on my set up for clearance. I think with a taller valve and different locks and retainers you could go over .700 lift with these. Bobby could this be a reality??
I talked to Tim at Hughes along with Kevin and they both believe that this casting will put the hurting on the sale of Edelbrock heads, and that the EQ Iron Rams will be used more as a replacement head. If these Heads FULL out will flow 320-340 CFM in the right persons hands, I could see it happening without a doubt.
