8v exhaust manifold help please!

I'm sure they're the same but please educate me if I'm wrong, but are the 1.6 and 1.8 exhaust manifolds both the same fit meant to the head? Can only seem to find 4 branch manifolds for a 1.8 not a 1.6, but of course If it fits then I'll more than likely buy it. Will it also clear the stock inlet manifold above?

Cheers in advance!
