i bought a set of the fast burn heads any one have any experiance with them thanks Greg

Rated in the magazines very well. It helps a zz4 short block out a ton. Good for around 35-40 hp, but just bolting them on. Put a hot cam and 1.6 rockers in a zz4 short block with these heads and you have yourself a 430 hp aka zz430 minus aluminum water pump and valve covers.

Has someone started making headers to fit the FAst Burns?

Now that's a good damn point Carl. I will search and see!!!! I called HEDMAN and they said they didn't have headers for them yet, they suggested calling the Performance Parts people.

UPDATE:

Just talked to Scoggin-Dickey and the Performance Parts guy there says that a standard small block header will fit on the FAST BURNS BUT.....the primary tubes have to be a minimum of 1 3/4" as per his NOTES section in his manual. I don't have fast burns myself so maybe someone else can confirm this???

Yours creates an interesting question also. There are some past posts on the need for custom headers for the Fast Burns but if standard 1 3/4" headers will work with the "D" port then all is well.

I'd hate to be the guinea pig on this. "Standard" headers never seem work on first gen f-bodies.

I would be really interested in running these if they are as good as AFR or Dart.

i was told standard small block headers would work i just bought a set of hooker super comp. ceramic coated headers i pray there ok they cost enough

Greg,

What size did you get?

Carl

i just ordred super comps. from summit i don't know the size

Greg,

The size thing Carl alludes to is going to be VERY important. If the tubes are not a min. of 1 3/4" then you are going to partially block the exhaust ports on the heads which could potentially choke down the engine at higher RPM's. In addition, you will be blowing out header gaskets and potentially burning your exhaust valves.

Be sure and check this before putting those headers on!!!

should i just measure the head exhaust ports and then the headers opening to make sure the header opening is large enough gm says some trimming may be required i suppose if there not big enough you have to ream them out a little

I just spoke with one of my customers yesterday who has a set on his 350. He gave me this warning about headers and the fastburn heads, he had Sanderson tube headers, cracked all over the place, says they are problem prone, won't fit most applications with power steering.

He changed to a set of Hedman headers, no problems with fit even with power steering, etc., work better, and are better quality all the way around.

He also says the heads felt like 50 easy horsepower right out of the box and even with the stock exhaust manifolds he started with, before timing and carb work. I've heard basically the same thing from other people I have built ignitions for that now use these heads on just the head change-over.

can any one tell me if the hooker super comps.are good headers and hows the fit on a 69 thanks Greg

Greg,

Just take the header gasket you are going to use and hold it in place with just the header bolts to see if it partially blocks the exhaust ports on your fastburns. Then take the gasket and compare it to your headers to make sure that the opening in the tube header match the opening size in the gasket.

IMAN,

I use HEDMAN on my BB 69 and they do fit well. I had to ding them just a little by the starter but other than that they work fine. I had them CERAMIC coated AFTER I dinged them which is one of those things you learn AFTER you do it the other way once!!!

Supercomps come in three sizes, 1 5/8", 1 3/4", and 1 7/8".

1 5/8" will fit A/C cars OK, the others will not.

I'm surprised that Summit did not ask or specify what size you required.

sr, hindsight is always clear, isn't it! My customer with the Fast Burns said the Sandersons fit well, but just wouldn't take even the stock engine's exhaust heat, cracked badly. The Hedmans fit and work just as well as the Sandersons, with no cracking.

He did say that a marketing person from Doug Thorley contacted him about using his car as the template for a new header set that would clear the stock power steering. He was offered this "deal". They would have his car for a short time, 5 to 6 MONTHS, and the new headers would be installed His "contribution" to the proto-typing was a mere $400.00, for them to use HIS car to make thousands of dollars selling the correct header.

I guess just loaning them the car has gone the way of the Goonie bird, lost in the ozone anymore. Used to be the header and other accessories people would build proto-types off your car, then give you a half-dozen production sets to give to your friends to get the word out on the new stuff, with an industrial sized "thank you". I guess that is now bad advertizing or somethiojng, but it always used to work years ago.

Iman-

That's exactly what happened to me at Hooker. I took the car there to prove that THEIR header was the problem. They said they would fix it. Yeah, right. Two months later they said to wrap the delinquent tubes. In other words, were not messing with our messed up tooling. Plus, I recieved no "Thank You" at all. This, of course, is after 4 months of arguing and posturing over the multiple sets I installed.

Stock manifolds are sooooo much easier.

Pace Pontiac sells a set of Hedmann 3/4 length headers for fastburn heads but they do not clear 4 speed linkages (I learned that the hard way, had to send them back). What is strange is Pace Pontiac sells them but the tech rep on the phone for Hedmann says he never heard of any fastburn application. Go figure.

I ended up with a set of Sanderson block hugger style headers that are meant for fastburn heads. I would have preferred full length headers, but then again people in hell prefer ice water if you know what I mean.

SOMEBODY PLEASE STOP ME BEFORE I BUY ANOTHER ONE!!

i talked to gm partech today they said what you had to do with 1 5/8 or 1 3/4 is to reem the flange to match the d shape ports

Excellent news!

Please keep us informed on the size headers you end up using and the amount of "customizing" you must do to make them work. You are treading on uncharted territory for us.

Good luck!

Carl

Greg, I have 1 3/4" Hooker Super Comps on one of my 67's with a SB. They fit awesome. Plugs, oil filter and starter are all easy to get to. I don't have PS, but they look to me like it would fit fine. My buddy had a 69 with super comp 1 7/8 with a SB, also fit good, I can't remember if he had PS or not. If you paid about $425 for your headers, I bet they are 1 3/4". Do you have the part #?

i called summit they are 1 5/8 but i think they'll be all right

I have to agree with Lonnie, I installed the Hooker 1 3/4 Super Comps on my 68 RS and they fit awsome. I have had almost every brand of header, at least all the ones they were making 5 or 10 years ago and the Hookers fit and work better than any ohers I have had!

Found a ad in a local trader mag, for a place called Jim Pace GM Parts Warehouse. It said, they have worked with Hedman, and designed a header for the Fast Burn, and ZZ4 D shaped exhaust port heads. Look for yourself, www.paceparts.com (http://www.paceparts.com)
