1g vs 2g vs 3g camshafts

[fourforty]

how interchangeable are the camshafts between the first second and third gen 4g63? i know the third generation 4g63 is flipped in the engine bay but would that matter if i am just flipping the camshafts accordingly? or would i need a 7 bolt head to use them on a 6 bolt block? also has anyone ever tried this before?

You can use EVO cams, but they aren't a direct bolt in affair. General consensus I believe is that it isn't worth the hassle. 1g and 2g cams are the same
