Here is the install view from the top. You’ll want to re-route the brake lines and the disc brake proportioning valve away from the headers of course. So, this was a good time for me to replace the master cylinder and get new brake lines.

Completing the installation of these Doug’s headers into my early A-body Valiant was a great exercise in patience and perseverance. Thankfully, through the help of Mancini Racing and Brewer’s Performance, Inc I was able to find the parts I needed to complete the installation. I am expecting a serious improvement in the exhaust flow over the stock manifolds. I will provide an update to this installation with a sound clip once I get the new Flowmaster exhaust system installed. Until then, thank you very much MOPARMAX.COM for opportunity to install the Doug’s Headers on my 1966 Valiant.
