1993 LT1 headers
I’ve ordered American racing headers off corvette central a few months ago but it’s been out of stock… almost everyone I’ve asked has said these are the headers to go with, and I’d like to get them, but I can still cancel my order for a refund and order a different set. I’ve recently been shown hedman headers however from youtube videos I’ve seen there are manufacturing issues/quality issues… if anyone can recommend a good set of headers let me know! Ideally I’d like to spend less than $1000 but I can spend up to 1500.

Go figure lol. I have no personal experience with the Hedman, but I did consider them at one point myself but for an L98 C4. I did not read the most flattering reviews about them. Conversely, the ARH headers you are waiting on are supposedly one of the best on the market. Have you tried calling the vendor to see what the hold up is?

corvette central emailed me saying it’s not available so it’s delayed… I also didn’t read the most flattering results, however on a stock motor or even a motor making 400 hp at crank, I don’t think the Hedmans would give me an issue? I’d like the ARP but I’m sick of waiting and want to get this build moving along so I’d rather get something else in the meantime

The Hedmans would most likely give you the same performance. Difference between them and ARH or Stainless Works is going to be the fit, finish and construction. The Hedmans won’t last nearly as long. Have you look at the Stainless Works? They are about 800 past what your max spending limit is.

Ive read of a few members here having them fit poorly and rot out after 5 years. I personally have not used them so I can only rely on the these other members reviews. Are the Hedmans you’re looking at meant for a L98 and you are modifying them to work on a LT1 with emissions?

correct, the hedmans are meant for L98 and I ordered some block off pieces for the EGR AIR and o2 bung , I already have ARP header studs to use on the headers I’m just not sure what route I wanna go for headers…. $260 on summit for hedman headers and I’d be perfectly fine with replacing them in 5 years for that price, but would it risk causing any damage to the motor ?

nah at this point I’d rather spend $260 on some hedman headers and if they break or cause issues I’m perfectly fine with buying another maker down the line, I think these hedmans will do fine for at least 1 year

Could throw a code, may not. A lot of misconceptions about EGR and performance. It’s not just to lower nox levels for emissions. It’s also used to cool cylinder temperatures. The LT1 runs higher compression. Removing it could lead to a slight lean condition and even engine pinging.

interestingly, their camaro lt1 headers are 1 3/4” (which wont work)
