I like the look but what about performance

There have been many tests over the years shorty headers V long tube headers on non Olds engines. The long tube headers have been a clear winner its not even close.
The stock 442 manifolds from the big blocks work okay 68-72. If you are looking to make HP above stock level long tubes are the way to go.
