Are you bracket racing, or heads up? If the ultimate power is most important, Stave V. If the most bang for the $ is important, E-brock

edelbrocks Victor jr's will do more than you need for strip street - but piston design can get tricky because of the changed exhaust valve angle. Also edlebrocks need a big bore as they were designed for the 4.5" bore blocks Edlebrock rep recommended a Min. Bore 4.375” - I am guessing they will work on a smaller bore but may require some additional work. My New HEMI is a 572 with the eddies and we will dyno it hopefully next week

the Hemi's have come a long way since the 60's. in the last few, tech is moving faster than ever. more sources than just one.

For the money, Indy big valve Hi Po Hemi heads....I have the flow numbers. Almost 460cfm if I remember...Call Bob George Racing for pricing. The Eddy heads, need a specific piston to not have interference issues.

Correct me if I am wrong but the only Edelbrock hemi head needing special piston notching is the latest edelbrock head with the big intake - the exhaust has a different guide angle requiring the special notch. The earlier edelbrock head sold through Mopar Performance ( with conventional valve train oiling ) does NOT need the special exhaust notch.

Yes, the Edelbrock Victor Jr. hemi head is the one w/ the different valve angle. The older Mopar Performance heads that were cast by Edelbrock are all stock style stuff. They just have the Edelbrock "E" cast into them under the valve cover.

The earlier edelbrock head sold through Mopar Performance ( with conventional valve train oiling ) does NOT need the special exhaust notch. Just because the valve angle is different doesn't mean that you need different pistons, or that it's going to cause you problems, etc. This isn't the 60's. Back then people would shave the heads and deck the block to get more compression. This would give you more compression but would decrease the piston to valve clearance. Most engines that people put together now are strokers. With a stroker you can get all the compression you want. Strokers take a lot less dome on the piston. Your street/strip application will probably be for pump gas and not have much dome. My guess is if you check your valve to piston clearance you will find you have a mile. When using Victor Jr's you do have to check the intake valve to bore clearance if you are using a small bore.

I have the regular ole Mopar Performance Crate Hemi heads on my 528". They flowed around 426 as cast on our flow bench but it still made 853/697 with only 10.5:1 on pump gas, so I am happy enough with them for now.

Quality on the E-brock valves, are they good for a.800 + roller cam?
