FITS PCM FORD AND PCM GM SMALL BLOCKS ONLY!
The blocked water passage goes towards the exhaust outlet.
The same gasket used for the 3" and 3.5" risers
Note on gasket:
Blocked end goes toward the rear of the riser. Open end to the front.
This way, more water gets pushed over the top so the exhaust hose won't burn at the top.
