No, not a disagreement Eric, just a difference of opinion. I have nothing against aluminum heads at all, but Im trying to keep Dusty's expenditures to a minimum...it's going to cost enough as it is. I guess I could have afforded aluminum heads a few times over, but I chose to put the money into other parts. My iron heads suit me just fine. If I were building a drag car, and was reaching for each 1/10 sec. Im sure I would be going about it differently. And I agree with you about how many guys are running iron heads...I'll bet it's not too many also...I just happen to know a few that do, and I guess I pay more attention to that, because you dont normally see that. So let's get Dusty set up and on the way. Pat, I think the 496 might suit him better too, but I believe he said he already scored the 427 tall deck block. John
