Technical Need a Positive ID: JR Headers for '55-'57 Chevy?

Hi folks,

I have had these headers in my garage attic for a while and was hoping to confirm what they fit. They look a lot like '55-'57 Chevy headers. Guy I bought them from said they were JR brand. All I know is they are definitely SBC, and very old (still have the driver's side alternator mount bracket). Thanks in advance.

 

no way... firewall is where the rear tubes are on those headers

 

You could be right...that looks tight to the firewall. Anyone else have an idea? thanks in advance.

 

Still looking for some help on this....

 

Send them to me for a test fit.

 

I had a set of JR headers on my '65 Chevelle drag car back in the day ('69). They had that strange down tube. They were originally sold for a '67 Chevelle dirt tracker. It took a couple hours to change spark plugs with them, so I got them for free.

 

Thanks, the Chevelle application could be a good fit. Now to find someone with an early Chevelle to check....

 

I have a 66 Chevelle.

 

Hedman bought JR Headers about 30 years ago. They may have some archived information on that part number

 

Thanks, I did contact Hedman but no luck on info.
