Manifold gaskets

I've got a 1989 1.8 8v cabby and had a new exhaust fitted, and it's still blowing at the manifold. Is the gasket 1 big 1, 2 long for 2 branches or is there 4 of them (individual) lease help before I buy the wrong ones

Normally it's 4 seperate ones - but you can fit the G60 single piece to save mucking about
