170 slant6 63 help

:thumblef:Thanks redfastback. I am getting ahead of myself here! but I have to do something and I thought I had better get looking and learning at what options I have to keep the 170 in the car. Clifford did not have headers for a slant 6. I see them on ebay but they are not sure what they fit.
I have heard the two barrel even gets better gas mileage and more hp.
I will continue my searching for info.
Thank you again redfastback:salute:
