I'm looking to find a set of headers to fit my 79 C10 2wd pickup, but the catch is. The heads have oval ports and angled plugs in them. I have searched and only come up with the 65868 headman headers, and I need a part time job to afford those babies. If anyone knows of any other headers that may work or a pair of those cheaper than $600.00 I would really like to know about them.
