I would get a haynes and chilton manual for your year, that has all the torque specs and clearances at the beginning of each chapter, very helpful. I cant tell you if the torque specs are different, but that firing order on that site is for NON HO engines, the firing order for our engines is 1-3-7-2-6-5-4-8, so I would recheck the torque specs.
I just checked the book and it says
camshaft sprocket bolt: 40 to 45 ftlbs
Camshaft thrust plate to engine block bolts: 9 to 12 ft lbs
so it looks like its the same but you should still invest in a manual, not that we don't like helping you, but it would save you a lot of time.
