TTI Headers
« on: September 27, 2020, 04:25:16 pm »
Once again, screwed by poor quality and fitment issues. This time on a $600 set of Hooker headers. Ports are off a full quarter inch, no way a gasket will seal.  >:(  Last time I built this truck I sent back three sets from different manufacturers due to fitment issues. Set number four were Sanderson block huggers. They fit and don't leak but the 1.5" tubes are too small for the upcoming 410" stroker. Plus the short tubes don't do anything for low end torque.

I don't suppose A, B/E body headers will fit? TTI's are supposedly top quality, but they don't make truck headers specifically. My truck has an o2 sensor, no leaks are a must, so shitty headers won't cut it.

    ...I dunno much about small block headers but I think Homer has a set of Doug Thorley(?) headers on his 360 that seem to be doing pretty well, but if it isn't a race engine I'd imagine a nice set of OEM manifolds would flow really good?

    410" stroker, Eddy heads, mildly bumpy cam, Eddy EFI. Be a shame to cork all that with a stock manifold. Long tube headers are worth about 30lbft of torque.

    I would suggest a header if you're building an all out, maximum hp build. For a truck that's intended for daily driving, you won't give up that much running manifolds.

    I used to always install headers on all my truck engines, thinking I'd gain extra hp, and they looked so much better. But over the years, my experience with headers has caused me to reconsider the header option. It didn't matter how much I'd spend, but headers were always a pain in the butt. Some just didn't bolt up right. Over time, they will leak or break a weld. They eventually rust out, even the stainless ones. They also caused other problems. Their proximity to starters meant that starters would often heat soak and fail frequently. Replacing the starter was another pain in the butt because you sometimes had to unbolt the header to drop the starter.

    As i got older, I just didn't bother and kept the factory cast iron manifolds. Of course this isn't what you want to hear. Headers do contribute to making more horsepower and torque, and if you're trying to get as much as possible, headers should be considered in any engine build. But if you aren't going to be spending much time at WOT, a set of headers will not offer too much of an advantage.

    When it comes to small block Chryslers, the later Magnum manifolds are actually pretty good, but if you want a bit better breathing out of cast iron, you may want to consider a pair of aftermarket cast iron manifolds. These are readily available for a decent price. They typically breath better then factory manifolds (though not quite as well as true headers) and don't suffer the problems of space, blown gaskets or heat soaking the starter.

    With your build not to say headers are a must, but it sounds like you will be disappointed without them.  I had luck with a set of headers from Summit.  No they are not stainless or fancy but they fit great on my 2wd. Seriously bolted right on to my 302 heads.   Mind you I keep it in the garage and out of the rain/mud so I am not too worried about rapid wear out.  I also wrapped them with volcano exhaust wrap.  Starter issue is easily avoided with the mid 90's "mini" truck/dakota starter.

    Yep. Thorley's made an awesome header. Very, very strong.
    I've been running the same Tri- Y set on my truck since '91.
    Unfortunately, they quit making them.
    I hope they last another 29 years, because I have no idea what I will do if they die.
