i've wrapped my headers with insulation, but unique users report that this will dramatically reduce the life of headers. i read the previous posts in this forum and still have no clear opinion of the truth.

one thing that made sense was that it wasn't the rust factor but the heat cycle that will cause the pipes to fail.

can you add any data to this subject. building a unique 289 fia, with a stroker 351 W

thanks
