I've heard the Edelbrock aluminum Pontiac heads work really well, anyone here used them? Are they as good as I hear?  

I'm staring long and hard at a set for an upcoming rebuild I'm planning for a spare 400 block I've got sitting in my garage. If you read up on the high hp build-ups from the builders like Butler racing and R & R Engineering, they use Edelbrock Aluminum heads. And these guys are getting 575+ ft.lbs. of torque (with different intakes and induction)- so I 'd say the heads are good.

Geno  

Yep.  Went 10.09 @131 with a set mildly ported by Indian Adventures (the original IA) in my 3400lb 1970 GTO with the stock rear suspension.  


They'll make a ton of power if you have the right combination.  

I found a set of Edelbrock 87cc's that have been mildly "worked over" with some bowl porting and never run for a very good price and installed them in place of my factory #62s on my Number matching 1969 400 along with the following items:

Comp Cam XE274
Roller rockers 1.5 (stock)
SRP forged pistons  (+.030)
eagle rods
Factory crank -3.75" stroke (-.010)
Balanced and Blueprinted.--Super time consuming and meticulous, but worth it!
RA IV oil pump.
CLoyes timing.
Performer RPM intake
Demon 750 Carb
MSD Pro Billet distributor
1 3/4 headers feeding 2-1/2 exhaust.
9.5-1 compression




Once all of this was together it turns out that this thing is stupid fast.   I was kinda hesitant about replacing my #62's b/c they are original and need almost no service work(with the exception of hardened exhaust seats), but now that the Edelbrocks are on it I have NO regrets.  They run cool, pull hard from idle all the way to whenever I get scared, and IMHO are probably making the engine put out around 450 HP at the flywheel and at least that much torque.

If you plan on doing any more than a stock rebuild and plan to turn the engine higher than 5,000 RPM then there are one of the best investments you can make powerwise.

 

..to run "at least high 10s" let's keep that in mind. Most of us that wanted to run "at least 10.90s" secretly desire to beak into the mid 9s with optimum conditions.....

Get what ever heads you decide to go with - Determine head flow numbers, choose a cam that will utilize the cfm (add a little cfm for x factor) Based on your lift make - sure your valve springs will handle the lift/pressure.

First, Aluminum heads (any brand/level) are 1/2 the weight of cast Iron - thus better 60 foot times (but are more money). Also, you can go to 11.00 - 11.25 compression with the aluminum heads - more power. Header costs are something to consider when cost being thought off - If you want better flow (need) then probably beeter to go with round port.

OK - The Eheads have been around for ever and work great - they should they were based on the Pontiac Round Port heads! But if you look at the CFM levels that can be purchased from Edelbrock versus the Kauffman Alum. D Port or the High Port Heads .... Kauffman are a better value. On the plus side of the Kauffman High Ports heads - they employ a better spark plug angle which improve burn. Using High Port Heads will need to use a 7" power brake booster for clearance (it's what I use) BUT most true racers don't have power brakes so it's not a problem for most. High Port heads will raise you manifold about an inch (most race guys have scoops/etc)

I think the Eheads are $100 - $200 more then the 330 cfm out-of-the-box Kauffman High Port heads that are build to handle .750" lift !!!!

I'd go with the new technology High Port Heads... room for growth, better, value.... plus the Kauffman boys are living the sport - what does the old Ehead Edelbrock guys have going on - It's not in their best interest. Kauffman are building products solely for Pontiac - and that's a good thing.

Final note: sorry for the book. Many ways to scalp-em. Guys that have been running iron heads and eheads have great combo's - nothing wrong with what's worked in the past. I just think you will have less guess work with KTE's D Port and HP heads.  

The butlers also sell those heads with bore and all to your needs I would call the with any questions you have they know what they are doing, Rodney and Daivd have had awesome numbers with those head combnations check out their site http://www.jbp-pontiac.com/index.html

I have a set of heads and cam that i need to sell.
kauffman Racing Aluminum D-Ports
Ferrea Stainless Valves,Crower Springs,CompRetainers,Locks and Keepers. ARP 7/16 studs.
ARP head  bolt kit included. Also Comp HR 110 HYD Roller Cam,244@.050 Int.-250@.050 Exh. All parts were spec'd out by Jeff Kauffman himself. Heads have 2000 miles on them; all that is needed is a set of new valve seals. This combo on a 10.5: 1 468 made 532 Hp on Dyno.

Decided to go differant way so I would like to sell them.
I would like to get $2400.00 for them.  

I have had 2 sets of Edelbrock heads. The first one was done by Bruce Fulper at Rock an Roll Engineering. They flowed 300cfm @ .600" lift. With 8.5:1 and a solid cam my 3900lb TA went 11.93@115 mph. I one a second set with complete engine from Hot Rod magazine. with minor bowl work the flowed 295 cfm. Had the engine reworked and heads ported a little more and they flow 317 cfm@.600" lift. I run a Butler 4.250stroker kit in a 400 block. .617" lift and 256/258 duration @.050. 10.3:1 compression. Running real fat I went 11.50@117mph on a 95 degree humid day. Needless to say , I love the heads for the price. They flow 280 cfm out of the box. Takes a lot of porting to get iron heads to equal the E-head. If I was going to run an IA2 block I would run the new CV-1 heads. They are designed for a larger engine like 500" or more. People are making 700+ hp on pump gas with a mild roller cam.

There is a lot of info there.Andy Mitchell at Outlaw Racing in Upland Ca. builds engine with those heads. How fast you go depends on how much money you send.  

Remember E-heads require RA 4 type headders. I have done research on other brand of heads and do like these the best for the money.  

Does anyone know what the flow rate is for std 62 heads?I've just replaced mine with a set of R&R Eng Edelbrocks and I'd like to know some comparison so I can reset my injection with a ball-park figure. I run a comp Altered in England. It was running mid 9's@140+ on methanol with a flying tiolet.  

The info I have says 212cfm at .500 lift.  

Remember,the cylinder head is only as good as the MATH behind the engine build. If u dont have proper cam shaft #s and the proper intake and carb combo, the head is not going to be able to do the job. The camshaft tells everything how to do its job. If you throw big cam #s into a head that has no work done to it (straight out of the box)it will b like trying to stick 10 lbs of crap into a 1lb bag but w/ proper combos, yes without a doubt Edelbrock cylinder heads work great.
