How many sets do you have? Thanks

gripit I just have the one set, they were used on a single engine (454) for one season, roughly 20 times in the water.

Sorry guy I'm unable to PM I guess, I've tried responding.

Headers were purchased new from Hardin Marine 6/7/2018 (have receipt), while I was out of state working, so they were installed that winter and ran on a single engine 7.4l for one season 2019 (roughly 20 outings none of which the boat sat in the water overnight). They were removed during an engine upgrade the following year and have been sitting in box since. Just cleaning out a shelf in my garage...
