I've been running Hedman Huslers for years and really like them. One tube on each side goes out through the fenderwell though.
I don't think it'll need the 4.30 gears
I was looking at those too but trying to avoid fender exit - not counting it out. Just trying to avoid it.
About ten years ago I was in the process of building my 408 and Ryan Johnson had my heads freshening them up. He and I were talking on the phone about the build and headers came up. Since my 340 had TTI's on it I was considering a new set of 1 7/8" TTI's for the 408. Ryan told me to go with Hedmans, IIRC he said they were worth over 30 hp on the dyno than TTI's, so I bought Hedman's. The easiest set of headers to install that I've ever owned, they are like a jig saw puzzle to put together though.
