Okay, I've got something that I can't seem to figure out. And I searched all the ways I could and didn't find anything. This may be a stupid question but I'm clueless: How do you loosen the cam pulley bolt without the cam itself turning. Don't have an impact wrench, I need to break this one by hand. Any suggestions? Thanks

long screwdriver in spoke of cam gear resting on surface of head....will work fine

 

You can also use 6mm punches inserted into the alignment holes in the cam caps/cams to hold them in place(also at TDC). Or, if your cams have a hex nut casted into the middle of them like LS cams do, you can use a wrench on that to hold the cam in place.
