whats the difference between x14xe and z14xe

[harry-nova]

i just bought an 2002 astra g 1.4 with blown engine will my x14xe fit in it and run

Fly by wire mainly. There are some differences in the inlet IIRC, ECU is obviously different and the astra will have pre-cat and cat and probably 2 lambda sensors. Aside from the throttle body which will need swapping everything else should either be ok or can be swapped from the old engine.

so just change inlet and exhaust and block and head is the same

There are some small differences but essentially the same - it should be ovious which bits of which you need to swap if any.
