Lindy,


I've fired off several fresh HEMI and B/RB motors with TTI headers in place having the brite finish TTI coating and experienced no issues with damage to the coatings, even in spots where I had to "tune" the tubes with a hammer/block for dimples for clearance and actually cracked the coating...TTI coatings are very tough, I'd just keep a watchful eye on then during break in, purchase a large high speed commercial fan from a local HD or Lowes to blast some air at the front of the car while running, helps also
