Displacement (ie 2.3L vs 2.0L) is stroke x bore. IF the bore is the same, then obviously the stroke is longer on the 2.3L.
Which in turn means that one of two truths must exist for the head:
EITHER: the 2.3L head is the same as the 2.0, the 2.3L will have a higher listed compression ratio than the 2.0L.
OR: the combustion chamber on a 2.3L head is bigger than that of the 2.0L
IF the listed compression ratios are NOT the same, then the heads are not the same.
Not saying that you can't use the heads, but you will have to compensate for the higher compression ratio by tune or octane rating or both.
