Evo, those last V6 Spiders had cams p/n 60603785 and 60603786. I don't have any specs on those, but seeing the made 192hp with a cat and 10:1CR, (engine # AR16101) I believe they were inferior to the 164Q cams, where the engine made 200hp with 10:1 and cat.
Richard, for the record, there were 4 more V6 (12v) cam part numbers, used in special 164 versions like the Brasil-bound cars and the tropical weather versions, but these were of no use to performance seekers. The 119xxx is the ancient AR numbering system used before 1989 or thereabouts and then translated/superseded by the new numbering system (remember the 119 series cars back then, most of the parts started with 119...) Strange you should mention the 3031 and 3033 numbers! These numbers alone (no 119 or anything else) exist with raised metal on the body of my cams, both pairs! Maybe I can take a closeup pic and post. I will look for the p/n you mention and see what I find.
As far as the 10.4mm cams, the CD's and Microfiches show they were also used in US 164's from '91-'93 (besides Motronic 75's and SZ/RZ)with engine # ARO64301. This engine was badged as 'USA 83' (an emissions classification) and was sold in Europe also.
Re. race V6 pistons, here's a pic of the 'right stuff' which I hope will be available again in an improved shape nontheless.
