Yes, rotate clockwise only, 1 full 360* & pin at TDC. Now bank 1-3 timing marks will flip upside down from prior position & now the smaller segment of the cam timing mark will face down. Install cams like you said, making sure to have all cam holding parts in place & torqued before releasing tension from Vario-Cam to cam chain. Then install gear sprocket with chain on exhaust cam with the special 10.9 grade bolts HANDTIGHT in the middle of the adjustment range.

Now install cam cover leaving oil pump & green cam plugs out. Next adjust cam timing with proper tool. Once timing is set slightly tighten exhaust cam gear sprocket bolts to hold timing in place & remove 1 bolt at a time, apply blue medium loctite & torque to 10.5 ft/lbs. Once all bolts are torqued rotate engine clockwise ONLY 1 revolution to TDC to check cam timing again. Repeat 1 revolution again to put 4-6 bank at TDC & verify correct cam timing for 4-6 cams. Install oil pump in head with 4-6 facing crankcase & coolant temp sensor.
New updated 4-6 chain tensioner will be a lower profile, perhaps for heat dispersion for A/C compressor. Tensioner installs with 11mm allenhead & has zero id rings unlike the others.
