edelbrock heads- gessler

ok I'm wieghing out the differences between head packages offered by gessler...

edelbrock- I've heard some very very good things about these, like they are getting almost TA stage 2- kinda numbers/results from them. and their price is right too... along with the fact that they accept SBC rockers which opens up selection and drops the cost even more.

VS.

stage 1 SE's done by gessler... they can make much better results, but I'm not totally sure what to do lol.

 

You got some bad info.

Stage 1 TA heads flow better than E brocks especilly on the exhaust side where Buicks need help.

TA Stage 2 heads flow even better than the TA stage 1 heads .

We have some head to head tests posted on this Board. http://www.v8buick.com/showthread.php?t=131278&highlight=flow+TA+heads+exhaust+side

If you do not need rollers. which is the case for most street engines, the cost of the TA stage 1 heads are only a little more.

 

you will make more power at a lower rpm with ported ta sg1 or 2 vs edelbrocks
the rockers really dont make it any cheaper as if you run to high a spring pressure you will need a stud girdle which the ta wont
they are cheap if you are running a street car around 550hp or lower

 

thanks for help guys.

I had someone tell me the edelbrocks were able to make serious power, but I'm looking for more than 500hp.

This a very nasty street engine I'm trying to put together, but I keep getting confused on stuff lol... or getting bad info, etc.:idea2:

This is also my first serious 455 build, and I just want to do it right... I'm looking for as close to 600hp on 93 as I can get. I've seen many other cars doing this, and checked them out, but haven't found quite enough info. I want to use the 308S cam, since thats the one I see in most of these mean street cars...

I believe that you will find on this board tthat AMP did a engine that made over 500 HP with a set of e-broks that were out of the box. I can also say that there is more HP in them than that. The exhaust port is less than great but withh the right cam it can be easily over come. MY bet is you will see a set in the 9's this year and a set that goes faster than that with a little help from a power adder.

 

You're right... and with a power adder and the right cam the exhaust port won't matter so much...

A boosted street motor with these might go pretty well...

But once again, I'm still leaning towards the level 2-3 TA's... for gessler's prices they are pretty damn hard to beat...

 

i got my ta sg1 se heads from trishield and they are flowing numbers just off
sg2 heads otherwise i would have dumped them for sg2s already
i will be making big power with these heads soon enuff

 

maybe i'm missing something here?? a good pocket porting and gasket match on iron stage I heads will produce better or as good flow numbers as the e heads for a lot less $$...just dosent seem to me to be worth 60 lbs

 

You're right... but if you fully port the edelbrock's I'm sure they'll flow better than fully ported irons... of course I could be wrong, gessler does some amazing stuff.

 

I have to agree with Larry on the iron vs aluminum ST1 heads. When I had mine done several years ago they flowed an average of 346/242 @ .600 lift 28". That was with a 2.16 intake valve. For comparison I had them tested at a different shop and the numbers were 339/238 cfm. Pretty decent for a head that accepts stage 1 headers and a standard intake flange.

My iron 71 St1 heads flow 269/204 @ .600 with standard Stage valves with street/strip porting. Matter of fact, they pretty much bottom out on the flow between .500-.550 lift.

If I was doing it over again I would go with Stage 2 TE with a larger intake valve.

Just my .02.

Happy New Years!

? i think you are missing something too?o No:
i do know that my ported ta alum SE heads flow almost as much as ported
ta stg 2 se heads so no power loss for me
i doubt even big port 430 heads with stage 1 valves and porting can match
just cleaned up ta alum heads
the e heads are good for mild motors but will need extensive work to make 600 hp or more.i beleive at those rpm/spring pressures needed for over 600 hp will be a problem for e head valve studs since they are only in aluminum
and would probalby need a girdle

 

Contact Gessler and get all his latest info on the edelbrock heads because he has run the tests. There are plenty of opinions out there on the edelbrock heads, I think you can find some good information if you search previous threads because I remember reading some that showed 550 HP with mild cam and port work. You can bet that people not running edelbrocks are going to suggest you not go with them, simple as that!
I can understand it too, but I know that a cam grind change can make up for different flow numbers. In a race engine with open headers and velocity stack the flow numbers will show the HP increase but on an engine that is corked up and street driven the HP is at the mercy of the exhaust and air intake.

It s fair to say the TA heads are a proven product, and that the edelbrocks will save you a good chunk of change. I have yet to see anyone try to reach the 600 Hp mark with the edelbrock's so the jury is still out, get the best information from Jim Bureck and Gessler and you will have the right information to make your decision. I have the edelbrocks and will not tell you you should use them simply because I'm no expert. I just think you should have the chance to listen to the gentlemen who have been testing them. This is just my opinion and I hope you have good luck with your build what ever brand you go with. :TU:

If the Edelbrock heads were better they would be in my car. Whether I have TA stuff has no impact on me giving a Board member the straight facts. Whether someone buys one brand or the other is their business as long as they get the straight facts they need to make an informed decision. That is what we strive to give members here.

Everytime you see someone say that they obtained a certain output with Edelbrocks they never seem to mention that with the same work the TAs would do even better because they are just a better design from an engineering standpoint. Also they are just a better quality casting.

From an economic standpoint, aside from the roller rocker cost issue which is not an essential for a steet engine, there is very little difference in the relative price points as a percentage of the total purchase.

 

I agree that t/a heads will flow better out of the box...i'm saying that matched and pocket ported stg I heads flow better than edelbrock out of the box...mine flow 270cfm intake 185 exh at a cost of 550.00 bucks and that is better than the e-heads...according to there liturature

I certainly have never said the edelbrock head is better or even equal, but that is the reason they are a lower priced. I believe that a cam with more exhaust in it can make up for the lower flow numbers, you can also go with more options on rocker types and ratios. I bought some of the best push rods and rockers made and still only had around 2,100.00 spent including the heads, I was looking at an extra 1,400.00 to go with the TA stage 1 and rocker set up. With the extra cost involved in building a 500 plus HP BBB the money saved can be put into the bottom end or convertor. I too believe in letting a person have all the information needed to make a decision and by no means try to say buy this one or that one. I just happen to own the other brand as do others on here and have great results. I have not heard you say one positive thing about the edelbrock head which is fine, I happen to think the more aftermarket gets involved in new Buick parts the better. Sometimes people can't afford the best, but can make up for it with the combination they use.

I think it is only fair that we give both brands fair explanation and not base it all on flow numbers and how pretty the casting is. That's all I need to say on the subject, they are both good products and have their place in helping Buick lovers improve performance. Happy New year to all.
