I'm putting my 383 stroker back together for my 80 El Camino & it looks like this one will wind up with 10.5-11:1 compression. It has been recommended to me to step up to 1.75" primary tubes. Was wondering what brand headers some of y'all are running. Right now I have an old set of Flowtech Afterburners which do just fine, but hoping the larger tubes will boost the power a bit. Any suggestions?
