85 TS6M PCM hissing when engine shuts off around intake gasket

I was at the lake diagnosing a fuel delivery problem and noticed a hissing noise around the intake gasket towards the middle of the gasket. There is a hole in the head that the gasket doesn't cover and the noise is coming out from there. I have taken a picture where the hole is. This noise also is active when running down the lake which sounds like a exhaust leak. Look at my fuel problem post and what I found out. I have looked on SKIDIM and they showed the intake gasket with a note stating that the hole was smaller for some reason or another. Maybe this will help.

I am almost proof positive that your intake should also cover that pen are of your crossover. That passage that is exposed is where on auti applications they heay the carb or air cleaner. You in take should be wider their and cover over that "flange" area!
