I have a 91 Caprice wagon with a 350 from a 93 roadmaster. I am looking to put headers on my car but i was wondering if anyone has who has done this can give me more info. Will shorty headres fit do i have to modify the shift linkage or will they hit the firewall? Here is the link to the headers on summit.
