    Which way up do the Pro 785 exhaust valves go in??

    i know this sounds dumb but I've spent 15 mins looking at pictures, forums and such and i cant figure it out. one way it fits better for the flow of burnt gasses. one way it seems like it would have better clearance from the piston and such

    im gonna guess they go the way to flow better with gases will it hurt the coating on them to drop them in carb chem dip to get the carbon build up off

    It can be confusing. They go the way you think that they might not.
