gasket failure

We all make mistakes,TTI included.I would contact Mike or Sam,Send them pictures of your problem. I had to do this on a "B" Hemi project.Passenger side fit fine.Driver side the collector was hitting the transmission pan rail.They sent another driver side pipe and fit was fine.They want to know if a problem exists so they can correct their jigs if they are off. Had this problem with Schumacher A big block headers on the passenger side.When notified Schumacher said they found that the jig was off 2 degrees and was glad to catch the problem.
