Skim the head until the face is level with the machined surface where the manifold gasket fits against the head. Hard to explain it but with the head on the bench you will see what I mean. That will give a compression ratio of 10.25:1 or very close, which should run nicely and still leaves enough meat around the water channels in the head. I've long maintained that the compression ratio is artificially low on the 1300, possibly to de-tune the engine and give the 1500 a reason for being.
