Attached is an extract from the Vauxhall college V6 manual which gives information on how to identify the different camshafts fitted to the Ecotec power plants.
Note, although it refers to coloured markings, often these are not visible so look for stamps in the camshaft castings near the pulley end.

A very effective performance mod on the 2.5 V6 is to fit the 3.0 inlet and exhaust cams, this gives about 18bhp more!
