Thanks for great info!
I am doing the same job and have a few questions please. Boxster-s 2001, 87K. Engine still in, tiptronic out.
I have bank 1 with replaced ramps and short chains, reinserted nicely and correctly at TDC, both the saddle and shaft-end hold down tools in place, CS slots correct, original chain tensioner reinstalled , cam sprocket bolted back on, cover still off. Problem is when I rotate crank 360 to do bank 2, I skip a tooth on the intake cam!!!!!

PCarBob, you don't go into the timing at all, but you do point us to Raby and Vu's video, so presumably you did this?
Is it possible that you were able to change ramps+chain without doing the timing and TDC rotations?
If you did do it per Raby video, any thoughts why I could be getting the slipped tooth?
Many thanks,
