Over the years there has been little discussion about the viability of headers. I once saw an English site advertising headers at $2000+, an out-of-sight price.

A company called Home once produced "shorty" headers for the recent model Thunderbird that just might fit our Jaguars -maybe. These headers are out of production presently, but did once cost about $550.

I have wondered if Sandersons might fit. I am not interested to pursue this further, but someone on this forum might be. Were I interested, I would contact Sanderson, determine if tooling was still available; and then send them a Jaguar exhaust gasket to see it matched. If everything matched, then mabe Sanderson still has a set in inventory to purchase Even if exhaust ports matched up, there still might be some minor clearance issued, but these can be resolved.

 

Opps. Site for header company was referenced as "home". Should take you to Sanderson Headers.
