Hello, As the title hints I have a 67 GS400 convertible and am finishing a complete restoration.. I am finding a REAL issue getting headers for the Buick Big Blocks. Can you recommend a make or even make and model number. Everything seems to be geared for a LS swap. The only change I have is aluminum edelbrock performer rpm 455 heads and intake. Any leads would be greatly appreciated. ALSO: Haha and I have a Brand New Set of [FONT="]Flowmaster 814116 Scavenger Headers 409S FOR Sale.. (FOR LS Swap) Live and Learn. Still in the Box. [/FONT]
