I use them.
I don't know what you want me to tell you though.
The engine I put them on in no way resembles a stock engine, I didn't do a 'before and after' comparison of performance.
They bolted on and seem to be working just fine.
Because they're aluminum, I went with a 10.6:1 CR.
Also because they're aluminum, I had inserts put in over the head bolt holes (steel) to give a crush-resistant, flat surface to torque against.
You should also realize that the exhaust ports are raised slightly in comparison to GT heads, though I believe they're about the same as CJ heads. When ordering headers, work with a knowledgable supplier and stress that you are using Edelbrock heads.
That's about it. I've heard differing opinions about the valve springs Edelbrock supplies with its heads. Seem to work. But I built for torque, not HP, so I don't rev that high. Your situation may be different.

Default FE E-heads

I have the first set of heads to come out of Edelbrock.The only problem with them is that the oil drain-back hole is angled directly at the gasket joint where the valley gasket&intake come together.Leaks like a screen door unless special attention is paid to seal that area REALLY good.Hopefully this problem was addressed in later production runs.

Thank's Guy's
Sounds good so far, I'm not building a screemer, but
concerned about weight and good flow(nice and new helps)
Useing a higher compression piston is an advantage from
aluminum heads.Good to get feed back on that application.

Thanks again Frank

Frank:


Got a set on my 454 FE (427 block with a 428 crank). Made 585 HP on the dyno on pump gas (some porting and polishing). I also have their intake. Buy the set w/o valves and springs and let your engine builder do the rest. Make sure you heli coil the R/A shaft holes.

Default aluminum heads

Hello Frank , I see your note and the mention of weight ...
I have a 428 in mine and by using the edelbrock RPM package I dropped 110 pounds off the stock FE using the RPM heads, alum intake and aluminum waterpump.
I have not recieved my car and have yet to flash it up.....I can't wait.

I'm not running them yet, but plan to. I have heard that they require quite a bit of clean up prior to installation (flash, burrs, etc.). Anyone know how much truth there is to that?
I guess it's not a big deal (clean when porting), but in case someone was just going to bolt them on & go without any machining, they might be in for a surprise.

Default edelbrock

remember guys, if your running 75% street and the rest race/play leave the porting in the semi-rough stage to hold onto the fuel stream and not polish to high lustre, if it's 30% street go with a high polish. it will help with street smoothness in the BB's.

Can you post more info on you build. Do you have flow numbers? You can send me a PM if you would like.

Thanks

Default Aluminum Heads

Frank

I purchased the Edelbrock Aluminum heads (Bare) part # 6008 over the bolt on ready to go set up #6006

I had heard from a few builders that the Edelbrock factory valve work, left alot to be desired. The Springs and keepers were not exactly what I was looking for either. I wanted Medium riser valves too instead of the low riser set that comes with the completed #6006 assembly.

I am just putting together my stroked 66 427 sideoiler (454) Alum Flywheel ,JE forged Pistons @ 10:7 CR, Eagle Rods, Aluminum Heads with Ferea valves with CS stainless rocker assembly with Billet end stands and Edelbrock RPM intake with a 830 cfm Holley chokeless race carb. So far it just looks pretty, I'll let you know how it runs in a couple of weeks.

I suggest you call George Gessford. He has alot of experience with these heads.

I'm in the process of putting my 428 together. I'm using the Edelbrock 6006 heads and the Edelbrock Performer RPM manifold. With this combination, the drip rails that mount under the rocker arm stands don't fit. There's too much interference with the manifold. I could cut away part of the drip rails but it would require a lot of trimming and it would seem to defeat the purpose of the drip rails. I plan on not using the drip rails at all. Has anyone else had the same experience?

G Gibbs:


Do not get the assembled heads, the parts they use are junk. Intake flowed 335 cfm at .650 lift, I don't remember the exhaust. 2.19" intake, 1.75" exhaust valves. Cam is 258 / 260 @ .050 duration, .619 / .626 lift (custom ground by my builder). 10.8 to 1 compression, Holley 950 HP carb. Also using Edelbrock intake. Made 585 hp @ 6,100 rpm and 570 ft lb torque @ 3,750 rpm on preimium unleaded. The trick is all in the heads and cam. Car idles at 850 rpm alll day long and never goes above 195 degrees in stop and go traffic when its 90 degrees out. If I missed anything, post more questions.

I had this problem as well. I found a set that worked, but now don't remember what exactly they came from...I had a bunch of different sets. But one type DOES work...medium riser, low riser, slipped on just fine.

I believe if you call Edelbrock tech they can give you the specific part number/application that works.

As for the stock parts used by Edelbrock...maybe I had a good machinist who wasn't looking to pad a bill, or maybe I got lucky, but he looked everything over and pronounced it good to go. I DID have a problem with the Shelby rocker setup which arrived miss-assembled.

Did anyone see the discussion in the Dove literature concerning the dyno test of the Dove single plane manifold compared to the Eldelbrock Performer RPM? Their claim is that on a 428 with Dove heads and a Comp Cams 294S cam, etc (fairly high HP motor) that their manifold made over 500 HP and the E. Performer RPM made 171 less HP. The manifold change was the only difference between runs. Does this seem correct?

CCX33911:

This is what I have found out about the Dove single plane:

I have spoken to 2 people who actually use one and who both say that they picked up almost a second in the 1/4 mile.

These heads could result in those kind of power gains - BUT- the power being made is at much higher rpms. If you look at the specs on the new (soon to be released - right!) Edelbrock Victor single plane intake which is a similar design, they state the useable rev range is way up there - something like 6000 to 8000 rpms.

I think I am going to stick with my dual plane.

I have built and sold more of these heads than anyone. I can tell you anything you need to know about them as well as the best intake to run for the application. When you have done these engines for 25 years you find out what works and what does not as well as what to use in any situation. You can ask 10 people and get 10 different answers because most do not know. Not rocket science on any of this just a lot of dyno time and track time. If I can help just let me know, I can sell you the parts to do ecactly what you want and make the power that you want.
I do engines so I will not tell you what to do about the foundation of your house or how to do brain surgery because I have not done that work yet.

Thanks, Keith Craft
