Marking the cam pulleys is meaningless other than for general reference only!
The cams are timed by pinning them and the crankshaft with the proper pinning tools.
The timing belt should be installed and tensioned with the cam gears bolts finger tight (snug) so they can rotate on the ends of the camshafts when tensioning the cam belt to self align.
There are timing marks with indexes on both the injection pump and crankshaft that should be placed in the proper position when timing this engine.
The cam pulleys can be held with a counterforce tool when performing the final torquing of the 2 cam bolts.
You can make a counterforce tool homemade, buy one, or rent one from a parts store. Plenty of them on line, just Google!
There is a five part YouTube video worth watching that is very helpful in showing you all the how tos of timing belt replacement....
