F body headers in an A-body?

i was just shopping around for headers, and the more specialized you get, the more expensive they are. all I've been able to find are schumacher and tti headers. those are way out of my price range, and I'm worried about the fit.
i know i shouldn't be so picky because of my situation, but i just don't like the "shorty" style headers. what are some other options? i know A bodies sorta evolved into f bodies which is why im wondering if they fit.
