    71221029K4 - Hooker Headers LS Engine Swap Conversion Kits is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Fitment I purchased this swap kit thinking it would be effortless. I also realize it's a swap so fitment could be an issue. However, with this particular "kit" the headers are designed around different motor mounts (dirty dingo). Because of this, I had to dent the underside on a couple primaries to clear the steering shaft. All was good an well. Fast forward 4 months and maybe 1000 miles. Everything has settled, now the header is making contact with the steering shaft. So I will need to either remove the header and dent the primaries even more or relocate the steering column where it comes from through the firewall. Jegs should definitely consider ditching the headers or offer the kit with dirty dingo engine mounts. Something else I'd like to add. Whenever you get the headers put a straight edge on the mounting flange. I had issues with leaking header gaskets on the passenger side. Found the flange was not true. I went to a machine shop to see if they could true it, they couldn't do it because the muilt-flange design. So save some money and get manifolds, or spend a little more and get the blackheart midlengths. Given those 2 options were designed around the mounts in this "kit".
