Summit Header opinion

My wife bought me the summit headers for my 67 ( at my request ). I read a number of posts here that said they were good and fit perfect, the price was right so it seemed like a good decision. I got them last night only to find the flange appears to be warped already, seems like a very poor quality design with low budge welds etc.... the flanges look like they could use a little more meat between the ports... can anyone comment on the performance of these headers? I know you get what you pay for, but I don't want to bolt them up only to find they will leak immediately.. can anyone confirm they work well without leaking etc??? your experiences and engine setup info would be helpful,, I plan on 400hp maybe a little more but certainly not over 450hp....

I've bought a couple sets of Summit headers and found them to be of good quality. Thick flanges, quality welds, no bends or dings etc. This was several years ago though. They may have a new supplier now.

If you're unhappy with them give Summit a call.

Re: Summit Header opinion

I did similar research not too long ago when I was header shopping. I read decent things about Summit headers as well. If I remember correctly the headers were/are (?) made by DynoMax. Ultimately I decided on Hookers Comps with Hot-Jet Extreme Sterling coating. Between the real cheep Summit ($100) and caddy Lemons ($1200) I decided on the middle of the road. I got the headers and they look good from an overall quality/workmanship point of view but I haven't put them on yet to see how they fit.

Re: Summit Header opinion

I have a set of the ceramic coated Summit headers on my small block. Bought them about 2-3 years ago. I have not had any leaks since I installed them and the finish looks exactly like it did the day I put them on. Fantastic purchase for the price. Was about 1/2 of what it was going to cost me to send my Hookers to JetHot, though I'm sure the JetHot coating is prettier.

Summit has the best customer service I have ever seen (outside of Costco). Return them if you are not satisfied.

Re: Summit Header opinion

If you haven't mounted them or ran the motor with them on and aren't happy, I'm sure summit will take them back without any questions asked, they are a very good company to deal with. I've had to send a bracket back twice, no questions asked.
If your on a budget, I run a set of ceramic coated hedman headers for sbc, they have thick flanges and thick tubes and have no ticks or leaks. They were under $300.00 shipped to my door and still look good after 5yrs of running, and multiple set ups, and being pulled from the car at least 3 times.
Don't know if they will fit your application, I have straight plugs, no a/c or power steering: http://www.summitracing.com/parts/HED-68278/
they fit pretty tight under the floor boards and I've only drug them on huge speed bumps when the car had iron heads, with aluminum heads I've yet to have them drag on anything.
Here is one of the pics I have of a side view, believe it or not the headers in the pic had been ran for 2yrs and they still look brand new, this was before the heads and other mods done to the motor:

The only Mustang I'd ever own is a Fender.

Re: Summit Header opinion

thanks for the advice, unfortunately, I do have AC and PS so that is one of the reasons I went with the Summit ones, many posts about a nice fit with those options... thanks again

Re: Summit Header opinion

I've also used the ceramic coated Summit headers with no problems. They fit better than some of the more expensive ones.

Re: Summit Header opinion

I have a set on my 67 that I bought about a year and a half ago. I like them. They still look good but I haven't run the car very much. The flanges looked a little flimsy to me too with welds that looked poor quality but they don't leak and they hold up nice. I also origianlly thought that the coating was a little dull, but after a few runs it got shinier and thanks to the advice of some of the guys on this site I learned to clean them with steel wool. The steel wool seems to polish them and they look friggin beautiful now. There is only one complaint I have... the tubes bend right over where the spark plugs go on some of the cylinders. You have to be a contortionist to change your plugs and you'll have to do some of them with a stubby box end wrench or an offset open ended wrench because a socket wont fit. Also because of this the plug wires are colse to the header tubes, so don't get plug wires with big plug boots or they will burn on you...it happened to me and I had to replace a cable. So my only advice is don't run Taylor wires with these headers. Use stock sized boots. But for the money, they are better than they cost and do everything they are supposed to do perfectly.

Re: Summit Header opinion

I bought the ceramics when they were on sale for around $170 and they were a great buy. No leaks and the fit my ps car great. The number six plug wire is a bit close but shorty plugs and MSD low profile 90 degree boots gives some clearance. The flanges are thinner than some of the top tier brands but the same as many others. If you tighten them enough to bend them then you probably have them too tight anyway. Yeah, I did (iron heads) but they don't leak. Just put them on, run them for fifty miles or so, then let it cool and retorque. The flange head bolts with serrated underside and 3/8" head work great.

Hey 67rs style did you put them headers on yet? I was thinking of pulling the trigger on a set. How do they look and fit?

Re: Summit Header opinion

I put a set of the Ceramic coated headers from Summit on my '69 1-1/2 years ago. No problems, although I borrow my buddies special SLP socket to change a few of the plugs. It's basically a cut off spark plug socket with the square hole drilled out to clear the plug,it slides down low so you can get a wrench on the flats of the socket.

Some videos I'v made for youtube

You make a good point. I use a 5/8" wrench on four of the plugs. Some people may be turned off by the spark plug access....although those type people usually get their oil changed at Jiffy Lube and pay to have their tires rotated.
