I just left off my rubber gasket and it seems to vent just fine. Personally, I don't dig the cowl style with the washer spacers on the hood...and that is coming from a former Mustang guy who likes cowl hoods. It just looks funny to me seeing the hood all jacked up with washers. I could understand if it was a pure race car running open track events, but in reality it is just a street car running a n/a truck motor.

With just the rubber gasket gone alone, the engine heat will defrost my windshield on cold days. More so on the driver's side, but you know how it is.
