Headers that fit?

[67 twins]

I'm looking for recommendations for headers that actually fit these trucks. I don't trust manufacturers fitment claims. I bought a truck that a PO had installed headers on & to accomplish this he had notched the frame & bent the zbar to sorta clear. When I removed them & looked up the part number on them the manufacturer says they fit. That's not my idea of fitment.
So that being said, I have a 67 with a 283 in the forward mount position & a manual transmission. I want to know what full length headers you guys have used with no fitment problems?

In my years of building vehicles,I have never found a set of headers fit without some tweaking,I have always used Headman Headers,usually fit the best,with minor tweaking

First I would like to say that your have pointed out the reason why I have stayed with stock manifolds. Your not alone. Do a search on here and most likely will find some good opinions about manufactures and model numbers.

Finding headers that fit without issue is pretty much an oxymoron. Take a close look on peoples builds.

My Summit headers fit with no issues at all. P/N SUM-G9006-SS.

Look at KOOKS Headers. Call and talk to Tyler Sandahi, 704-768-2288 ext:228. He is very good. mine fit great.

My first C10 was a 67. I installed some cheap headers on it, and they fit without notching. I don't remember the brand, but i think i bought them from JCWhitney in 1996. I installed Hooker headers on it a few years later and had to notch the frame. The 67 frame has less room for headers than 68-72 frames. I suspect manufacturers don't take this into account when designing headers. My 68 came from the PO with headers already installed, and no notching was required. I don't know the brand, but the tubes are smaller than my old Hooker headers.

I have had no issues with headman on my 68 k10 and no issues on my dads 72 k10 with hooker headers
Both are 4 speed trucks
I think engine placement also plays an issue as a rwd places a v8 further forword

[tim_mc]

Good point..my V8 is in the I6/4x4 V8 position further back.

Here's a photo of the factory notch on my '68. My '67 did not have these factory notches.

Although these are more money than most I've read that they fit with no issues.

Sanderson does have some that fit great. I bought the mid-length ones. Can’t remember the exact model number. I do recall them being very helpful when I called though.

I used jegs brand headers. Fit well except I heated 1 tube and whacked a dent in it on passenger side. Besides that, I actually tried no less than 4 sets and none came close to fitting. It was ridiculous.

Why is there no sticky with a definitive list of known headers that fit??

Sort of like a known wheel fitment, offset, and drop thread on most forums.

My son bought a set of Hedman short headers, not sure what the short part meant other than maybe the length of the tubes coming down the side. I had to just grind a small amount of frame, I mean less than an eight of an inch, off to get them to fit. Other than that and a poorly bent brake line that needed a bit of adjustment, they fit pretty well. They sound good too. I will say the bolts to get them to tighten were a pain as you have to get them all started, then tighten each one a small amount as you go. If you tighten one or two all the way then the others hit into the pipe and won't allow you to thread them. Not a big deal, but when you are bent over and have sausage fingers it is a bit of a drag. LOL

Remember tube size plays allot into if a set slides in and bolts up, or if you need to tweak them a little.
Small tube headers that are a slide in, bolt on are not going to gain you anything over a set of 2.5" exit corvette ram horns . Other than that pinging noise of the exhaust in the header tubes and the bolts backing off &gasket leak headaches that many headers suffer from.
speedway motors sell the repop vette ram horns, iirc for 120 a set.
