does a non turbo 1.9 head fit a 1.8 turbo engine-any advice?

Nope.

why wont it last long. it is only the size of the ports your changing i presume.
how can that make it so it wont last long?

turbo and non turbo heads are not the same metals, and moreover the turbo head is somewhat stronger in the casting.

so you could fit a head from a turbo diesel xantia. then just used the standard 1.7 td head gasket as required.
sounds like a plan.
the ports are the same size 1.7 or 1.9. so all the difference is in the casting. i will have to look into that.

So if you didnt know what engine they came off, how is it possible to tell the difference?
