455 Headers

I would first of all like to know the best seller to go to for headers for my 69 Sky GS I am putting a 455 into.
:beer
Next, I would like to know if anyone has an idea wheather headers made for an a-body for a 455 like for an olds, would fit my application?
I think you all understand where this is going, so thanks for the help!

If it is for the street

I'd go to TA for shorty headers. I HATE to hear the flange hit EVERY little bump you encounter.:af:

I would expect the the OLDS thing would work if you replaced the head flange, but I dunno???o No: Seems like a lot of extra work & welding...

 

You'd be re-inventing the wheel. It seems to me that for all that effort you could just build yourself custom headers from scratch

 

Scott,
As was said above the TA Shorties are the way to go for a street car, keeps you from dragging the collector flanges on every speed bump in town. They are well built, heavy duty pieces.
You'll have to bite the bullet though I think I paid close to $400 with shipping, and that is for uncoated headers, add another $200 for the Jet Hot option.
I had mine Aluminized (flame spray aluminum) locally for $100.

 

Headers

:beer Thanks Len,
I appreciate you helping me see the light. I just wish I were taking a trip to Cali so I could buy some of what I need and carry it back with me instead of forking out all that shipping $$. I know I am cheap, but all that adds up to like the cost of some serious mods I could make vs paying some rediculous S&H charges. I wish there was the slow boat to china option.
Aloha,
Scott

 

I've got the regular long headers on my '69 convert. and have Never had a problem scraping the flanges on anything

I did however have to slightly bend one tube onear the steering link and grind off piece of the upper control arm mounting tab on the passenger side

I'd HIGHLY reccomend getting them coated seing as you're surrounded by salt water. JetHot used to have a deal that if you got them coated NEW from the manufacturer (TA in My case) the coating is covered for life. Mine have been back once so far for recoating and will go back again in a few years - all it costs is the shipping

 

Speaking of 455 headers... anyone have experience "adapting" headers to fit the 455? I've got my dad drawing up the dimensions and exit angles on his spare 454 Chevy that I'm going to compare to the 455....

Reason being, mine is going in a 55 Chevy wagon (some day when the Mopar gets off my back <grrrr>)... and I know I'm going with fenderwell swept. It seems it would get me close to snag a pair of BBC fenderwells (readily available) and make a few cuts and alterations.... including new flanges of course.

I'm only shooting for around 400hp... would 1 7/8" primaries be ok or should I look for something larger? For that matter, I have some 1 3/4 SBC fenderwells for it hanging on the wall LOL

 

Have adapted a set of chevy sb headers.
They are very close, 2 reartubes was a direct fit, 2 fronttubes was moved a little forward as a pair.

The angle of the tubes to flange look a little weird, because of the buick exits 45 degree down, where the chevy is almost vertical.
Expect to make the flanges yourself because of this

 

What brand and part number did you use to adapt to the buick 455. Could you please post that info. I am thinking of making something like what you mentioned.
