cost. unless you would like to say 400 plus for the 80 snout and what ever the flanges go for these days.
with the flange the y pipe and air boxes are post back toward the firewall by the thickness of the flange which sometimes will result in air boxes not being fastened to the original mounting points on the valve coves

For the stock plenum you will need to cut off and bore to 82mm then find a plate to weld onto the plenum to screw into the 82mm tb
The sl55 plenum will be 80mm

you can port match the 74mm inlet to the 82mm and then add material on the top to mate it to the OEM MB 82mm
like this. cleanest and most cost efficient way to mate a 82mm to a factory inlet

In the pic you can see the bottom mounting position is OEM (74mm inlet)
