Unhappy N8A and N9A Engine Difference

Hi everyone,
I have been an owner of the Sierra 2.0 for a couple of months and just noticed this brilliant forum.
However, I am having issues with my n9a engine and changing the engine completely is way cheaper.
My question is can I use the bottom end of the n8a carbureted engine and use my n9c cylinder head?

I would be very thankful for your answers.

Cheers

N8 is carb models, N9 is injection

Bottom ends are the same if I remember correct.

Thanks very much for the answers. The engine is dead now because the timing chain snapped. Before that the engine was burning oil about 1 litre for 250 km. Because the rebuild of that engine is extremely expensive I just thought of buying an engine from a crashed car which is way more cheaper thank rebuilding the old one.

Edit: I asked because I was not sure about the bottom end of the two engines. Some say there are differences. But I think the differences are just in the cylinder head ?! Injectors, etc...
