In and almost done... have to solve a clearance problem as the drivers side collector is hitting my shifter cable hold down, collectors are really close to the trans pan. I would have preferred to have them sit a little lower. Passenger side was a lot easier to install than the drivers side. I also wish the bolt holes on the head side flanges were a little larger other than that they seem ok. I now see why the bung holes are in the outside not really much room on the inside.
