ok so i got a little update for the next guy who finds this thread using the search.. i talked on the phone with belanger header and venomus 1 was RIGHT there is a slight difference between the quad and single cab trucks, you can tell what ones you have by a "S" stamped on the mounting plate above the front spark plug for standard or a "Q" for quadcab.. i did have the right headers so i was instructed to inspect my motor mounts and sure enough apon a closer inspection i found that my right side motor mount bracket (the part that actually mounts to the block) was totally mangled and cousing the right side of the block to sit low! so turns out im a moron and notched my frame for nothing...
