Looks like a dual plane design too, would have good torque for the street Sent from my CPH2197 using Tapatalk

wow now we are talking ,looks like that suits std 460 heads,cobra jet are a lot bigger than that im sure,i also learnt from reading heaps of stuff is 90% of the gun aftermarket manifolds only suit cobra jet and super cobra jet,blower manifolds ect,but that one is a good price with carbs.

Quench heads will deal with higher compression if set up right (zero deck, flat tops, etc) as they keep the mixture moving during combustion. My 302 is at around 10:1 and it's very mild. Only sees a bit of knock when hot and at low rpm/high load. Sent from my CPH2197 using Tapatalk

I think the hump and the guide would benefit greatly from not being there, the rear of the port I don't think is too bad. Cant be any worse than a Windsor Sent from my CPH2197 using Tapatalk

hey these d3ve a2a irons get a good wrap on you tube and other forums ,just some patient work can really arc them up for factory head,the d3ve a2a is the first of the emission heads with a big bump on the exhaust which must be blended at least or removed as it has something to do with emissions,on the intake side they only need a clean up,but the exhaust is choked and needs some nice porting ,even most go the cobra jet exhaust gasket mark it out and start grinding,they are around 92 cc to 97cc and with a sealed power flat top gets you into the 10.1 zone with milling of avarage 30 thou to get zero deck,but the earlier DOVE AND other early cast irons have a closed chamber and an easy 10.5.1 is had but too much if anything these days,factory cobra jet irons are hard to come by even in the states,very interesting all this big block stuff.

I didn't buy the media because the guy at trade tools said your compressor is to small so I just tided the manifold up a tad and Tuesday will take it too the pro's,I will get em to blast the bare heads too so I can have something to do,1973 cast on the manifold yet D4 at the front.
