is within some type of spec range. Our plenums don't really bend as much they have a tendancy to break/chip/shatter. I think the addition of silica in the metal's composite may have been some of the cause for that. Most plenums I have/had (if I had to guess, around 60 or so) have always been around the same clearances according to their approriative years. After Z32 collisions I've seen the plenum crack, smash into a few pieces, etc...but large amount of mishappening...nah.
Anywho, like I said probably the picture distorted just a tad.
