I should think that you may have to be guided by emissions testing.
The 62/63 cams have an extremely short intake profile (163deg. @ 2mm lift).
The 08/09 cams have a profile more in line with the rest of the US spec cams (179deg. @ 2mm), and would be my choice.
The 26/27 cams are unfamiliar; are they from a late 560? 1986/87 560s were fitted with 18/19 cams (187deg. @ 2mm), but with a late intake lobe center (120deg. ATDC) to reduce overlap and unburned HCs.
