Adjusting Valves on 24 Valve

I'm going to adjust my valves in the morning. I read that setting TDC can be done by the altenator nut. To me with all the compression on these trucks that doesn't seem possible. Can anyone confirm this is a good way to do this?

Yeah thats how you do it.. Some guy has a website and he has AMAZING step by step tutorials of this.. Im sorry but got a new computer and now dont have it in my favorites.. I cant remember but pretty sure someone will jump in and tell you it hes also a member on here. Also im going to be doing mine here pretty soon.. Did you have to replace the valve cover gasket or can you reuse them??

Intake is closer to the intake side an has smaller rockers exhaust has larger rockers,I did mine two weeks ago truck runs quieter and smoother when you check the clearance check it between the bridge and the spacer it's really easy cyl 5 and 6 are tougher but it's worth it my truck had 190000 when I did em the other day
