I have a 69 Cutlass S with a 350 and want to replace the original exhaust manifolds with a pair of Hooker Competition headers. Does any one know if this selection of headers will fit ok?

 

I think that any headers that say they are for a small block olds should be ok. Is the motor built? U might have to redo the exaust to fit the headers, but what kind of performance is the motor making. Built, bolt ons, stock?
