Assuming Heatran 31 Speed IV, 0 Speed EVs.
Timid = 106 Speed.
Modest = 97 Speed.
Scizor:
Jolly w/ 100 Speed EVs = 107 Speed.
Jolly w/ 36 Speed EVs = 99 Speed (98 is skipped).
Adamant w/ 172 Speed EVs = 107 Speed.
Adamant w/ 100 Speed EVs = 98 Speed.

Heatran:
Timid = 209 Speed.
Modest = 190 Speed.
Scizor:
Jolly w/ 100 Speed EVs = 210 Speed.
Jolly w/ 32 Speed EVs = 191 Speed.
Adamant w/ 176 Speed EVs = 210 Speed.
Adamant w/ 100 Speed EVs = 191 Speed.
