early a body headers??

Im interested in putting headers on my 66 dart, but uninterested in cutting my inner fender well, and more uninterested paying around 700$. Ive been looking at some "block hugger" style headers and it looks like it can be done with some possible alterations done to the primaries on the driver side? Anybody ever tried this? And if so how did it turn out?
I had very good luck with my atempt. 63 Dart 340 727 manual steering. Just sold them to a member via eBay. They can work with some creativity. I made up some long tubes for mine now and didn't need them anymore.
