Stainless Steel Headers good or bad
 
i have been thinking of getting stainless steel headers for my 1972 chevelle Malibu. i have a 350 cid engine but im not sure whether the s.s. headers will cause exhaust leaks while the engine is warming up and is running due to the different expansion rates in the materials. can someone tell me if s.s. headers are more of a problem causer or a good idea. and if anyone has any other suggestions on what type of headers to use ur help will be appreciated. thanks for the help.

I too would like to hear from someone with SS headers...? I`m sure they move a considerable amount when heated but do they also change color as I suspect...? Also is the mounting flange stainless also...? If so do they use a special gasket for them or a simple graphite type...?


I should change my sig to read "fetish for stainless... :D "

They are the best bar none, the thicker the better. No problems with expansion since it is only nickel added to steel. If you can afford it go for it, you won't be sorry. Stainless handles the heat better without the decarburization problems that plagues mild steel in the same application. I think all the manufacturers should switch to all stainless construction just for durability reasons alone, if everyone bought them they would be cheaper.:) The also seem to take longer to cool off kinda like a cast manifold due to the conductivity difference.

The Jet Hot coating seems to work well also. Not sure of the insulating qualities and if it helps prevent decarburization of plain steel.

Willys might know? He has had good luck with Jet Hot on his Willys headers.

Headers for 1972 Chevelle 327
 
I am looking for headers for the Chevelle I am working on. I plan on putting a 454 in later, but for now I have a 327. I don't want to cut any of the inner fenders to clear something that doesn't fit. Can anyone suggest a manufacturer that makes a long branch header that will fit without cutting?

This thread is like 7 years old :eek: Are you wanting a set for the SBC you have in it now or the BBC you are planing on installing later? But to answer your question you can can about any header company and tell them what you have and they can hook you up with a set of full length headers, Myself i like the Hooker Super Competition. But there are several other company's out there that have good stuff also. But if you are going to a Big Block later just leave it alone till you get the BBC in there then worry about it then. JMO

327 headers
 
Thank you, it makes sense not to spend the money now, but wait for the BBC. I will pass on the recomendation on the Hooker headers for later use.
