Default torque setting question - valve covers, rubber gasket

Sorry for the question, just want to make sure I don't need to do this valve cover again soon.

85 L98 - Based on the advice of the forum, I bought the fel pro gaskets that are rubber with a metal plate in the middle. The instructions say torque to 60 inch lbs. Would this translate into 5 foot lbs??? If so, that doesn't seem like a whole lotta torque to me.. but I want to be careful because I've been warned about over torquing.

Can I just use a torque wrench that is designed for foot pounds and torque to 5, or is this not going to be accurate enough? Thanks.

ps I am still trying to figure out why my haynes tells me I had to remove the alternator to remove the valve cover - the air pump bracket is what is really in the way.

1 foot/lbs= 12 inch/lbs

ie 10 ft/lbs = 120 inch/lbs

so yes 60/12 = 5

Because manuals, especially those like the Haynes, are often full of doggie-doo. Common sense and experience should often prevail. Yes, 60 lbs.-in. does calculate to 5 lbs.-ft. Put a little blue Loctite on the bolts and retorque after a run-in. You should be good to go after that.
