What about ported Stealths? I figure they would come around $1400 as well, but would it flow more than stock box RPMs?



Still not as good a deal as a set of EZ's that really respond to a minor cleanup with stock port window.You can get them around $2000.00 give or take a few hun depending on who you get them from.



The CNC-ported Stealths are $2000 a pair from 440source and the flow table looks good, 321 cfm at .650-up lift... how do the EZ's compare if they're the same price?



My EZ's are not CNC ported as they were just cleaned up a bit. They are Max Wedge size and flow 340 @ .650. But I am surprised to see Steaths flow 321 @ .650 as I have not heard of them flowing that good. Ron



Here are the flows from our bench on the out-of-the-box standard Stealth and then after some serious porting. It is why I say if you already have ANY aftermarket aluminum head, you don't need to buy another head to get 750 HP. Why buy another head that you will still have to port to get 750 HP if you already own a set of aluminum heads? If the Stealths can do it, which heads can't?
