I'm looking into installing some headers on my 500 caddy in my 1980 crewcab and could use some advise. From the research I have conducted I believe the only alternative is to use BBC full length headers and weld them to a 500 caddy header flanges with starter tubes (either 1.75 or 2.00 dia). What are my options for headers (brands) and what size starter tubes would be best suited for my particular application. I'm really don't have any experience with this sort of thing. thanks in advance.
