I’ll tell you how maybe YOU can find that out on your own. Go to your local parts store or website in your country and look for a rebuilt cylinder head for both the 2.3 and the 2.0. If they are the same listing, then they are the same part. If they aren’t the same part number, they aren’t. Same trick works for bore - piston part numbers.

My normal go-to in the USA is Rockauto but they don’t list a 2.0 for the Mazda 6 in '03.

It’s largely the same engine. The 2.3L is for the most part a stroked 2.0L The head shows different part numbers, but some other parts (oil pump, head gasket,valve springs) do interchange. So some parts are the same some are not.
