Full length headers on a stock 350 HD?

Hey guys!

Local shops only seem to carry full length headers or block-hugger type headers.

If I buy a pair of longtubes with 1 1/2" primary tubes, will I suffer from any negative effects? I keep hearing that you can loose some low-end torque. Would the top-end gains be worth the low-end loss? This is a stock 350HD in a 85 3/4T 4x4.

I'll use the block-huggers if I have to, but am worried about heat.

I'd prefer to buy through my local exhaust shop for warranty reasons.

Any info would be great! Thanks.

I think you are a bit mixed up, full length headers produce the best gains in both low end and high end. Next come equal lenght "shorty" headers, block huggers produce the least gains. Try to spend the extra coin on a ceramic coated set, not for the performance gains(mostly hype) but because most coated brands offer lifetime warranty against rust through(dynomax does, I have them and like em).....actually, I will be selling my small block headers in a month or 2 possibly.....they wont fit with my new motor hehehe(dont tell any one.....its a secret[img]images/icons/wink.gif[/img])

I might just be intrested in that set of headers of when you do you "secret" engine swap. Let me know what you want for them and what not.

Either Four Wheeler or Peterson's 4 Wheel & Off Road just did an article on headers this past month I believe. In one test they put a heat gun on a "painted header" and then a "coated header" they said the coated header was only 1/2 as hot as the paint (like 250 vs. 500 degrees I think)
