Most of that makes sense to me, so now to the next question new head -$8,000 and “recon” head 4,000 so what’s Cummins doing to recon a head testing for cracks and cutting new seats essentially replacing the valves and “cleaning” the deck without actually removing material to not “change” the compression ratio? Not saying that’s the route I’ll be going but definitely something to consider
