I wanted to stay with the stock rocker arm geometry and stock exh port location which the EZ head does. The Victor uses offset rockers and raised exh port so I believe it has more potential then the EZ heads for a strong build. I have never used the Indy Victor heads but I hear they are a good head. As for me I like how good the EZ heads are and can keep all the stock dimensions. Ron Last edited by 383man; 08/23/12 07:56 PM.

Typically the difference between the Indy small port and the big port with offset intake rockers is about 20 to 25 cfm. The bigger port window will make another 50 to 60 hp in a maxed out combo, but it requires an aggressive cam and more rpm to do it. I don't know how the big Edelbrocks stack up, but should be close to the 440-1 for power. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

In my opinion it depends on several factors, ie. what are you doing with the car, street car, drag car, what header you can fit, how heavy is the car, is this the biggest motor your going to build, what is the rest of the combination etc. Everyone wants to go for max flow, they forget about numbers accross the lift range. If it a street car you don't need a head that flows 370 at .750 lift unless you want to run a loose converter and a 4.56 gear on the street. You will need to run a pretty aggresive cam to take advantage of that type of cylinder head. I'm getting ready to buy a new set of 440-1s because I already have the oiling kit valley plate, rockers head studs, etc. and they will give me room to go bigger in the future. My car is a dragrace only tube chassis car. You might look at the Indy SR head also if you can deal with the raised exhaust port, better exhaust flow can be achieved than on the EZ head. A lot of people don't look at the exhaust flow just the intake.

That much power would push your car down the track just fine. www.arengineering.com then click on tech articles.

You will need offset intake rockers and more than likely going to need new pushrods. Whomever you have set up the heads should be able to help you with cam choice. The motor should make some stout numbers and easily run low tens, if you can get it hooked up with a small tire and not tear up the 8 3/4 rearend.

They are just way too long to make peak hp. With high stall and 500+ CID at 3000 lbs you don't benefit from the 4000 rpm torque they make. Think about 2-1/8" (or stepped 2 to 2-1/8) that are only 30-34" long. Likely to get you 30hp peak improvement.
