headers
I am looking into header situation, and came across, https://www.ebay.com/itm/OLDS-CUTLAS...-/182850971141
I like the look but what about performance

I want a set now since I have the old ‘headers’.
Just saw these on eBay from Thornton. They are for sale now in two different finishes.

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.
