Greetings '64 Custom ,
I also have a set of the Langdon headers you mentioned. Can you send or post a sound file? If you need to email it to me and I can host/post it to my web page service for everyone to hear.
Also interested in what mufflers you went with and how far back they are from the tail end of the exhuast pipes.
If oyu're looking to squeeze every drop of power from this motor I'd say the Long-tube headers. If it's a mild build and you're looking for the sound go with Langdon's cast ones. I just put them on my '64 and they're sweet. Make sure to go full duals for the sound !!! "
