As long as you have an accurate wrench and a a crow's foot to reach a couple few that are hard to get at .. then yes it's a good idea.

I don't know if you have the factory bulletin about their weak azz blocks ..
#9 and #10 when torqued to 40 ft / lbs pulled number six cylinder out of round and they had to replace quite a few powerheads.

But they recommend , 1 - 8 go to 40 ft /lbs

And you leave 9 - 10 back at 25 ft / lbs



Port side , directly under number six cylinder ...
