12mm wrist pin includes everything in the photos plus wrist pin and clips (not shown). exhaust gasket NOT included for some reason...sorry!***note: the ports are quickly chamfered out of the box. you'll wanna go over the ports and clean up the chamfering to make things super nice before running it!******note DO NOT OVER TORQUE THE EXHAUST STUDS. the flange is quite thin by design and will crack or break if you over torque things.***
