i have been running 351w headers from summit racing on my 306 just because there the only header i was able to find to work. they are wider at the bottom compared to a 302 header but the driver side header does hit the steering box.
now upgrading to the 347 i want to do this right with the correct headers for my application.
so who makes long tube headers to fit in a 67 with an 347-AOD
