Are there any visual differences between an M30B30 and an M30B35 engine?

[AlexanderM]

Silly question perhaps, but besides the engine size written on the intake manifold, are there any glaring visual differences between the two engines?

Thanks.

There's a 3.5 embossed above the oil filter mount on B35 motors.

I think they also have a different intake. I know for sure that the b28 does it has a different volume plenum
