Headers for '67 SB

Dan · April 1st, 2004, 04:39 PM

Does anyone know what headers will work on a '67 Cutlass small block? Every place Ive found only goes back to '68 for small blocks and '65 for big blocks. Will the '68 headers work? Summit has them as well as many other companies. Maybe someone knows where to look that I am not finding. Any info would be appreciated. Thanks

Dan,
Try Sanderson Headers (www.sandersonheaders.com) They may have what you need. You may want to consider installing the correct dual exhaust manifolds for the 67 cutlass. Some may disagree with me bit I have never had good luck with headers on an Olds if I use it as a driver. The bolt pattern on the exhaust manifolds will not apply a uniform clamping force on the flange and the headers will leak.
You can get the correct dual manifolds reproduction for a good price now. Big Block manifolds will fit the small block engine. Just use big block gaskets to prevent the gaskets from burning and leaking.
You may also be interested to know that the dual exhaust manifolds for the Big Olds uses a cap on the right manifold cross over.
Good Luck

Kooks is the only company that makes headers for your application. They're expensive, but the quality is outstanding. They're light years better than Hooker headers.
