Would the H74500Ex that you listed in your Cayenne DP (Diesel Power?) cam post work, it looks similar to that profile? Or am I just assuming untrue things about your product coding system?
Sorry, that should be an 'H74500EX", not "M74500EX", and it is a Hydraulic lifter profile.

And MadBill was right, the DP is for Daytona Prototype, and Porsche did not like getting beat by their own engine.

Interesting. Do you happen to remember what the base circle diameter is for those Porsche Cayenne cams? Also, could those profiles be run on a 35mm hydraulic tappet?

Ok so Boxter and Cayanne have 33mm lifters so these should fit on a 35mm lifter just fine.

Yes, they'll work on a 35mm hyd tappet.
Base Circle on the Cayenne cams was 1.440"
