Denting headers for clearance.

Thank you everyone for the feedback and yes the headers are uncoated so I’ll make the dings before I get them ceramic coated.
Perfect, I heat 'em 'til they're orange and use a piece of heavy wall black-pipe or such and drive it into the area with a nice BFH. Take extra care to heat it plenty in the area
of that weld on the weld itself to keep from causing a crack adjacent to it. Enjoy Your newfound clearance!!
