I bought the hedman shorties for 135.00 and the y pipe for 95.00. Ordered from summit, jegs is back order on the y pipe for about 3 weeks. I also to summit that jegs has 1-2 day shipping for free, they were going to charge me 30 something to ship.
I bought the Hedman emmisions things with y pipe for one cat for 349 including shipping. I could not find the ones beedo got when I ordered. No coating. LT1 sure looks good on my garage floor.
The best headers are the Hedman 68479 for the painted and 66479 for the coated. These headers have the d-ports and also will clear the angle plugs as well. They have a matching y-pipe that fits like a glove. You will have to buy O2 bungs and have them welded in either the headers or the y-pipe though.
do you have the part #,s I was think of geting hedmans and have them cerimaic coated here and are they D port and will they clear the angle plugs thanks
just go to summitracing.com and search for 68479 or 66479. Hedman makes a long-tube d port header too.
If you don't get ceramic coated then buy header wrap and put it on. Header wrap is probably more effective anyway but i'm no expert on that. Definitely cheaper.

i have heard that also, but rusts the headers out quicker.
well for $405 I can get the 66479 ceramic coated cause it has to look good mine is a 86 IROC I had for around 20 year park in the garage it had 17,000 when I got , it was in a flood there no rust on it at all and dont know if it a keeper I had a new 69 camaro SS 396 and since 78 a 55 chevy Belair 2dr htp with 350 all ceramic front to back on exhaut and 410 posi it all done so sweet I wouldnt sell this one and the iroc I puting a 94 lt1 with 4l60E trans for now it sit on engine stand I still extending the wires on the wire harness plans are for 373 gears well that the plan
i have heard that also, but rusts the headers out quicker.
I think some people spray that 2000 degree spary paint on them and it seals the header wrap better to prevent rust. I don't know if thats total BS or not.
The old HS mechanics teacher always said if you don't coat em, them wrap em.
Stainless steel headers(SLP?) with ceramic coating with header wrap would be the ultimate.
would the hooker headers for the 94-96 impala ss fit? i was talking to the counter guy @ the speedshop out here and they said i have to run the impala headers to keep it smog legal.
the headmans, ARE they for the 93-97 LT1's cause the info i read on summit said they wee for GEN I LT1's, Does it matter? Im not too keen on the headers.......
THanks
Hedman 68481 (painted $359.95 at Summit) or 66481 (coated $618.99 at Summit) smog legal in all 50 states. Shorty header with y-pipe from what the website looks like. Will fit angle plug heads as well. Best fitting header I have found for the LT1's going into a 3rd gen car.
shorties suck, come on, there are no good long tube + y-pipe combos in 1 3/4 for this car??? ****, yet there are like 5 or 6 long tube header options for my GTO.
Hedman makes a d-port longtube header too, I think. Hooker longtube super comps will bolt up, they are 1 3/4". Search around on summitracing.com or jegs.com. Any thirdgen (82-92) header with 1 5/8" primary minimum made for a 350, shortie or longtube will work but as Klortho said, the Hedman shorty d-port header with its ypipe fits the best.

Shorties keep the torque band where they are from stock, by the time you swap to the 6-speed crossmember and put long tube headers on the car you have major clearance issues. The Hedman's put everything back in the stock location and fit like a glove.
Plus he's in California as well and those shorties are the only ones that Hedman show that are 50 state legal.
And 1 3/4 are a waste on these motors anyway, the 1 5/8 to 3" primaries are just fine and I know alot of guys putting down a ton of HP though that size header.
why didnt anyone mention dyno dons headers? Seems like they would flow better being that they are 1 3/4. i would think 1 5/8 would be fine for a long tube but i would rather have the 1 3/4 on a shorty.
Also I noticed 66481 headmans are oval port and that wont work on a d port head. I just sold a set of headmans for 50$ for that very reason.

The correct part number for the d-port angle plug headers are 68479. 1-3/4" headers are over kill for these engines since the ports on the heads are 1-5/8, you would have to hog out the exhaust ports just to keep the step down from happening which does something to the exhaust and kills performance, can't exaxtly remember what it is, but I read it somewhere on here about it.
He was needing smog headers, and the 66481 were the only ones that Hedman had listed with smog provisions.
It creates turbulance. In theory, its so close to the head the gas is still expanding so it shouldnt much matter. do you have a coated number for non emission d port?
i have a set of flowtech afterburner headers...theyre full length headers and theyre meant for any small block chevy v8...i dunno if you are looking for anything like this, but i'm selling them with a set of aluminum gaskets for 150 just to let you know....

damn!!!! i want to get rid of these damn headers...someone sold them to me swearing they were shorty headers and they obviously arent and i'm pretty pissed....i just wnat to get rid of these so if anyone here knows anyone who wants headers for cheap with all the hardware i.e. top of the line aluminum gaskets and bolts please let them know because i just want these gone!
Will they bolt to the engine, yes. will they work, no. Its not something you want to buy to use on this swap since it doesn't cover the ports correctly. I tried a set and they leaked like crazy.

Thats funny, i've used them twice on two different swaps and neither leaked, nor were the ports off enough that it would come close to leaking, maybe you had a warped set, the difference on the ports was around 3/32nd of an inch.
I know this is a old post but does anyone know if they make a y-pipe for the headmen long tubes

For my longtubes I got a drews xmember (skulte makes one too), a flowmaster Y collector, and then took it all to the exhaust shop to have them weld it all up to my mufflex 4inch catback.. the ground clearance now is just as good as my shorties used to be..
the size now is dual 2.5inch - single 4inch - dual 3inch out spintech muffer..
As for the edelbrock TES, it worked fine for me with no leaks, but kills the power above 330 or so rwhp.

Here are some pics. The first shot is looking forward you can see the longtube collector tucked up nicely..excuse the slave cylinder I am in the process of machining down the mounting plate. The second is from the side of the crossmemember, as you can see the lowest point is the crossmember itself.
To get the exhaust in I still had to notch the a-arm mount and lift up the passenger side of the engine.

No, it is around ten degrees in my garage right now. I just ran out and snapped them. In a few days I will heat it back up when I put the slave cylinder back on and take a few more then.. any specific section you want me to focus on?
Ok guys im a little confused I was told any headers for an 82 - 92 camaro will fit the Lt1 as long as long as they were 1 5/8 or bigger. I just wanted to know why some of these dont work, also i had my heart set on a full mac exhaust so im wondering if these would fit??? please help i was litterally going to order these tomorrow and im going to hld off till i know for sure.

As long as they are 1 5/8 D port. The exhaust on the lt1 is 1 5/8 d port shaped. you will need at least 1 5/8 D port or 1 3/4. I recommend 1 3/4, since they don't even make 1 5/8th headers for lt1 F body's to begin with. Dyno Don makes some excellent headers for the swap.

Uhh....yeah Hedman has a d-port header for third gens that has a matching y-pipe that can be bought and they're for angle plug heads.
