I already bought my heads for the next decade, so I've no interest in buying the EB heads (or any other for that matter). But there may be an interest by people not wanting to or able to spend more cash or use up their credit card limit: Home porting would be a lot easier with the softer aluminum, or a head porter would spend less hours on aluminum and therefore charge less. No one will be sure what the bang-for-the-buck will be until they come out and someone jacks with 'em for a while. (But I agree that just playing odds, they prolly won't flow much better than stock stage 1's before porting). They'll stand or fall on their own merits. This thread is now LOCKED (yeah, right).
