ive never seen an 87-89 BANSHEE, let alone one with an original head. get with the fuckin times..
so youre saying, that since i havent torqued mine since 2001, thats not enough time for it to warp??? what point are you trying to make here? at most i would ever go without taking it off would be a year, and most people would be doing the same..
your point sucks. it makes no sense. move on.
