No shield ( or gasket ) on the pass side of any mopar small block.

Look for an OEM part number on the drivers side shield.

McCord did both sides and nether one had an OEM number on them

my money is on they're aftermkt shields

And as an FYI not only is the center divided on the 340 shield. But the exhaust port openings are actually taller on the 340 shield over the 318 shield
