Does, or did, Indy make two different versions of the EZ heads, M.W. and 440 port sizes? I have a set of the 440-EZ-1 on a motor I'm building for a local customer that has the intake M.W. size ports like the SR M.W. heads have but I believe that these have the stock 440 exhaust port size and location, not raised like the SR and not nearly as big as the 440-1 heads have This motor is the same as yours will be, 512 C.I. 400 block bracket motor with a Indy 400-2 intake and a 950 CFM 4150 carb. that the customer has.

ez's have a raised intake port and stock location exhaust port. indy extended the intake flange a little to allow for a stock manifold. So stock type manifolds will work on this combination?

So stock type manifolds will work on this combination? yep. the intake port flange is moved inward to compensate for the raised ports, but this will raise the carb pad height as compared to stock port locations heads.

I'm using an Edelbrock Performer RPM with std. port EZ's and it fits under the flat hood with a 3" drop base air filter. I really like the std. exhaust port location so you can use off the shelf headers. I was very pleased with the way everything bolted on and my Isky rockers only needed some very minor trimming to get them centered over the valves. If you're using a modern style rocker they will probably line up just fine. Make sure you get the valve job checked by a reliable cylinder head guy. Two of my guides were tight and a few of the seats needed to be touched up. Sounds like it will be a real brawler Mine with a stick shift is a real handful when I'm deep into the throttle Gus

I am running the non-Max Wedge port Indy EZ's on my 440 block with a stroker kit. The carb flang is raised slightly(maybe 1/2"), but I can still run a Shaker hood.

I am planning my next engine build. It will be a 512 stroker using a 400 block. I have a set of Indy EZ heads. I've had them about 10 years (bought new and never installed on an engine). Are the Indy EZ heads from that era taller than an Edlebrock head? This engine is going in a 68 Charger/Auto and I want to use the stock hood. Also, whats your opinion on these older heads? Would they be as good as a modern Eddy or 440 Source head?? Thanks Since it is a 400 block you should be just fine. The Indy heads move the intake up but a 400 block is shorter so you probably end up in the same general location as a factory RB block. Your other question on EZ heads vs. other heads is tougher to answer. I'd say that if you're going to run standard port heads then the Trick Flows are the best option. But you would need to sell the EZ heads and buy the Trick Flows so I'm not sure you want to do that. The EZ heads work great when opened up to MW size. As a standard port head they aren't great since they are really a MW head with a plug of material at the face that necks them down to a standard port size. But if it is just a street car they'll work just fine. Like I said, not an easy decision. Since you're building a 512 you could open them up to MW size but then you have to run the 400-2 intake which is fairly tall. Nobody builds a low deck dual plane MW intake which is what would work great on your car. You could get someone to modify a Performer RPM to fit on MW ports but it would cost some bucks.

I don't have a Victor383 but I do have several 400-2, I could measure from the mounting flange down to a flat suface with the intake sitting on that if that will help If so let me know Don't forget that the 400-2 is Max Wedge internal port size from the carb to the head mounting surface, the Victor 383 is 440 port size, which means the intake port hieght is shorter than the 400-2

Its a bummer they dont build the Indy dual plane for the low deck. I use the Indy dual plane with my EZ heads on my 440 block and its not to tall when compared to most single planes. Be nice if Indy made the dual plane for the low deck. Ron
