Currently produced Headers for the 94-96 LT1/L99 cars.
*If you have a header, current or discontinued, or info that should be added or corrected, Please PM me!!
This is for Parts reference only. These might not be the cheapest locations to get them. Figure prices as a ball park. Also some offer options such as EGR, AIR, Hook-up pipes, Cats, different coating types.
*Note that some offer the option bolt in, some don't. Prices will be given for both if possible.
Header Parts of interest
*Header gaskets, for the head flange.*
Earls Pressure Masters
For Tri-Y, Budget heads, Quad-1's, or Long Tube Headers. Generally regarded as the BEST sealing, and lasting header gasket. There is a metal frame that the header and head sandwich. There is a soft Material "insert" that does the actual sealing. These inserts are replaceable, and the frames can be reused. Might be a good idea to get extra inserts incase you have to remove the headers, and the inserts won't re seal. There are other options, but these are very proven. In many cases, you only have to retighten the header bolts once, with these gaskets. Other gaskets tend to require tightening a few more times after heat cycles. *note that they are a THICK gasket, and might cause header to frame clearances on some headers, such as the Flowtechs. If this happens, you might try a thinner gasket, such as felpro's, mr gasket, percy's, etc.
Earls are not your only options. I will be adding other options as I get the correct part #'s sent to me.

They have 12pt 5/16" heads. More clearance to get socket or box end wrench around. Why buy 12 when for the same price you can get 16 ( just incase you lose one)

*Note that if they are not coated, they are either Raw steel, or painted. If they are painted, the paint tends to burn off. The paint is intended to keep them from rusting in their box. Unless the headers are Stainless, it is strongly urged that you have a coating on them. And even then, there are different grades of stainless. some better than others in terms of retaining heat, and not rusting. The coating does three things. 1. Keeps the heat in the headers, to protect other items under the hood, like wiring, sensors, spark plug wires, A/C lines, etc. 2. Protect the headers from rusting. 3. Potentially help the car produce more power by retaining heat.
There are different types of headers, for different situations. Some locations require your headers to be C.A.R.B. Emissions Legal. Some retain the factory Cat pipes, and Cats in the stock location, and some bolt right to the factory cat pipes. Some require custom pipes to bolt to the factory Catback, and Some offer it as an option.
There are also different headers from a performance standpoint, such as shorty's, mid length, long tube, Tri-Y, or 4-1.
It is generally accepted that long tubes are the way to go for the most performance, and that the only reason to use shorties is if your emissions test requires it, or you just can't bring yourself to use a non bolt-in setup, an can't afford the lng tubes that offer true bolt in. It is also generally Accepted that Tri-Y's will make the most power until around 5000-5500 RPM, and then past that 4-1 headers will make more power.
Summit Performance Headers: $90
Painted, check next listed. These look like JUST like the black jack headers.
Summit Performance Headers, Coated: $190
Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs. I'm 99% sure these are the same as dynomax's 85001/86001's. There was a guy who does many LT1 builds, claiming they will fit. I have Sucessfully installed a set of these. I am still not 100% done. Link below.
Dynomax Black Jack headers: $130
Painted, check next listed.
Dynomax Headers, Coated: $325
Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs, Minor fitment issues on some cars. Sometimes hits the passengers side frame rail, which could require minor grinding of the weld bead. May require clearancing the brace on that side as well.
Flowtech Afterburner Headers: $186
Painted. Check next listing.
Flowtech Afterburner Headers, coated: $326
Long Tube, 1 5/8", 3" collector, steel, coated, require custom hook-up pipes to the factory catback (See Note), No O2 sensor bungs, unless purchased from Jet Hot, Minor fitment issues on some cars. Sometimes hits the passengers side frame rail, which could require minor grinding of the weld bead.
*Note: Clear Image Auto now offers Custom hook-up pipes to the factory catback. But they do require some Fabrication. They also offer a Custom "X" Cross over that bolts directly to them. See parts of interest.
Grottyhan Headers: $550
Long tube, 1 3/4", 3" collector, steel. These are Grott copy's. They are not exactly the same, but quite close. These can be had coated, I think. You will need some custom made hook-up pipes. I don't have a site, but Mike Harris shared the info in the link above.
