Finishing up my TB/WP & cooling hoses. Question is on the accorn nuts that hold the valve covers down. When i saw a shoulder on the bolts that these nuts go on, i surmised that these accorn nuts bottom out meaning you take them all the way down to the shoulder and then torque. Now that i'm doing this with a new gasket, just pulling the cover down is surpassing the manual stated 7 lbs and got me wondering if this set up is designed to be bottomed out? The two nuts in the middle of the cover do not have a shoulder, so i assume these are simply snugged down. (?) TIA.
