Volvo 480 ES cylinder head swap

I bought a 1988 Volvo 480 ES yesterday. The previous owner tested, for how
long does the original timing belt work. Well, the answer is 173000 km
(108000 miles).
The Volvo dealership estimated, that removing and fitting the cylinder head
costs about 500 euros. So, I bought a used renault engine for 30 euros. I
am going to put the renault head on Volvo engine. Any idea, if is it going
to work? What kind of timing belt should I use? I have a Swedish market
Volvo, fuel injection, no turbo, no catalysator. I am aware that the
compression ratio may change. Is the original head worth of repairing?

Thanks for your attention,
