Comments about Flowtech Standard Header:

86 Chevy C10 LWB with a 350. Live in northwest Indiana and it has lasted two years, some surface rust but they are still solid. Original paint went from black to a rustic red after the first hard drive. The box has two reducers which take the collectors from three inch down to two and a half so you'll need different collectors if you want three inch pipes. A 45 degree pipe up and another 45 takes it back over the trans cross member, two thrush cherry bombs and a 45 degree out puts the exhaust about 10 inches in front of my tire. My exhaust note is the reason liberals cry themselves to sleep. 'Merica

      Better than expensive stock manifolds. Comes with all hardware. Installed on 1984 Chevy K 10 350 4 speed. This one fit the manual trans without rubbing clutch linkage. I talk to guy on phone and he said there is another part # for auto trans.

          Bought these headers locally even though I had heard some mixed reviews about them. Had isses installing them but finally got them on. After hooking everything up I heard a ticking sound. I replaced the gaskets four times assuming it was the flange not sealing. I then found that it was a faulty weld at the collector. I returned them for another set only to have the same problem. Dont skimp on headers, buy a quality set.

            Comments about Flowtech Standard Header:

            Ordered these headers after having problems getting OE exhaust manifolds. Spent a fortune on nuts,bolts,gaskets etc. only to find out the exhaust dumped out right on the motor mount and would be extremely difficult to install.

            I returned them and ordered the Flowtec headers.
            I was very pleased to see that the kit included everything you need to get these installed, event the collectors and gaskets!

            Quality was good , however there was a bit of surface rust on the pipes. (Cheap paint..) however I repainted them before installation.

            Everything went together better than I anticipated, the hardware was decent and the exhaust dumped out where it should with plenty of clearance.

            I highly recommend this product as a direct replacement for factory manifolds.

            Advanced shipped the item in a timely manner and I even got a special discount that saved me an addition $15. Thanks Advanced for offering a great product and service

              I changed the motor in my 1977 Grumman-Olsen Curbmaster Jr. step-van. (like an ice-cream truck) It has a 1/2 ton chevy chassis. It came with a Chevolet 292 cubic inch 6-cylinder motor that had a cracked block from being overheated. I pulled out the six, and modified a right motor mount as the 292 had staggered mounts. I had a good low mileage chevy 350 that I had built for a 1979 Chevy 1/2 ton pickup previously. I installed it in my driveway, having to insert it thru the passenger door opening, as the hood is only about a foot and a half long.I had previously changed the turbo 350 transmission to a 700-R-4 overdrive trans which helped the problem with overhating somewhat. But a freeze-plug that was extremely difficult to get to prompted me to go ahead and pull the motor out, and put in the v-8. I needed exhaust, and had previously had a set of flowtech headers, but the passenger side was lost, so I checked out stock exhaust at other outlets, and salvage yards, but the prices were too high, so I went online looking for headers, and found them at Advance Auto Parts. I got a discount coupon code online, and picked them up about an hour later at my local Advance Auto Parts Store, brought them home, and they went right into place. I finished hooking up all the lines, wires, ect. and the little truck runs great, and sounds like a hot rod.

                  I'm happy to help, Duce7! Your 1982 Chevrolet C10 5.0L 305 CID V8 likely has straight plug cylinder heads. The best way to determine whether if you have angle plug cylinder heads is by checking the casting number on your heads. You will also likely notice that the spark plugs are inserted into the head at an angle, rather than straight in.

                  I'm happy to help, Rick! These Flowtech Standard Full-Length Headers do fit a 1979 Chevrolet C10 with a small-block V8. Depending upon the features your vehicle has, you may need to make some modifications or require additional parts. According to Flowtech, your truck will require A/C Bracket Part No. 10042FLT.
