New guy here hello ... i own a 76 buick regal v6 but im putting the soul off a 75 455 cutlass in it im looking for exhaust headers and advice on my project and any other cool parts any body might want to sell.

 

New here as well.. It just so happens I'm about to list some 455 longtube headers I removed from my 1970-455. They are sand blasted and finished in hi-temp primer. There are no distinguished markings on these to determine manufacturer. They can be yours for $80.00 + shipping to you.

 

Hi, I'm no expert, but those headers look just like my Hooker headers, model 3902 below. Does yours have a "pinch" on the number six header tube like in the third pic? This one is from the factory for clearance of the mounting bolt.

 

I installed a 455 into my 85 Cutlass and had no luck trying to install early 70's headers (big or small block)... I decided to use W/Z Manifolds with 70-72 cutlass/442 front exhaust pipes, and 85-87 442 mufflers & tailpipes... Only modification needed was an extension pipe from the front exhaust pipes to the mufflers and a little bending of the front pipes to clear the cross member....

These headers do not have the "pinch" point at no.6. There is a slotted hole there unlike the others. They seem to have the same flange though.

Probably better off buying year correct or custom for the Regal install...
