They did not. Still working on it. They had a very nice cfm gain vs a stock apache, and the cnc is even better BUT I also wonder where these will land price wise vs a new, already awesome, stock 6.4 head. A new mopar 6.4 head can be had at any dealer for $1000.@Johnny Mac did they announce a price?
Is that $1000 for a set of heads or for each? Also looks like they come drilled for left and right exhaust manifoldsThey did not. Still working on it.

@408 swinger is correct. 800-1000, with usually a 200 core. Ea. So out the door 1000-1200 NEW.Is that $1000 for a set of heads or for each? Also looks like they come drilled for left and right exhaust manifolds
I have zero skin in this, but have you personally flowed these AFR's on your flow bench? They had the flow sheets on these right in their booth at sema, with comparison numbers to eagle, apache, and the early heads. These were up around 15-18 cfm as cast, peak, vs apache if I recall. So I'm just curious as to what basis you know their claims are false. 18 cfm is a mathematical increase last time I checked.they do NOT out flow 6.4 heads. they claim 50cfm+ but thats compared to an early 5.7 head. you csn tell by the giant *** cumbustion chambers. as esrly 5.7 had the largest deepest chambers. they flow about the exact same as my 6.4 bge heads unported.
thiteks for win anyways
my 6.4 bge heads(2.14/1.65) in pic to show you the shallow chambers vs those deep pre eagle 5.7 chambers on those afrs
