How much horsepower do headers add to a 350?

Well built headers
To be honest these were a nightmare to install but that’s on me because I took a guess while ordering headers for my 72 Pontiac Ventura. Though it took a lot of massaging to get them in I can guarantee I was much harder on them than most people will be and they are stout. I had to flatten both the #5 and #6 tubes just a hair to clear various components and it took some work with a very large “adjuster” to dent them. Very very solid built. Gaskets are great, they even include well machined 3/8 header bolts to make install easier and it was. Everything that was included is very well
Made so even though my project was a pain I have to rate these pretty high especially for the price though I wouldn’t recommend these for any GM X-bodies with power steering and A/C but it is doable.

Finally a good fit
Bought this about a month ago after going thru 3 other sets of headers to try and fit my 91 k2500. These fit like a glove (although I did have to remove a heat shield along the cab on passenger side). Fit right up, came out right where I needed em to. Although after having them on for only a few weeks and driving around only a small handful of times, the black coating burnt up and it looks a little rough now

350 mid headers
These headers came with everything you need for a good install however, they do NOT mount straight to a 193 head, the bolt holes on cylinder 7 and 8 are a 1/4 to short and require modification to properly install. I suggest making those two mounting bolt holes adjustable to allow clearance for the bolts to go in straight.

Good Quality
After a long Google search, these were about the only header I found that were 'supposed' to fit my truck ('94 Sierra w/ 5 speed 305). After a very easy installation, I realized I could had EASILY put full length headers in there. I can't conceive the reason why it wouldn't fit.
Cut off part of the PS/alternator bracket, remove the spark plug mounts on the heads and grind a little off the dipstick mount and that's it!
Buy Mr. Gasket header gaskets and coat with Permatex UltraCopper...never have an issue. (re-tighten header bolts several times too)

Fit nice
Bought these for a 1990 Silverado 4x4, they fit perfect and look nice, not quite ready to fire it to hear them but they should work. Was short one bolt but not a big deal got one a local parts store. Would not hesitate to buy them again.
