    Has anyone installed one of their manafold back kits?
    I have one I would like to install on my 84 K2500. My only concern is the heat riser on the passenger side. Will the kit work with it, or do I have to remove it... use a different manafold... etc.
    Contacted Heartthrob and they said they honestly weren't sure. So, hopefully someone here has gone through this before.
    Thanks!

    Sounds like they are a repackager / reseller, not the developer. Maybe look around and see if you can find the actual manufacturer to buy from.

    Most of these kits use the same donut to the heat riser as the manifold, with the stud length being a concern because its not always threaded 100%

    My hope was if I have to loose the heat riser I can set the donut in the manafold and go that route.
    Yes, I'm sure the studs have a non threaded shank and would need replacement

    The heat riser and the manifold on the ones I've done all had the same bevel cut for the donut
