Sliding the head nuts down to the studs, using a long thin screw driver shaft , makes things easier. There are TWO nuts under the rockers.... so if you don't see 'em? You need to take the rockers blocks off ! And.... torquing them down crosswise. I like to sneak up on the torgue spec ...give the head a few TAPS with the mallet, then finish off torquing it down. Let the head sit for a while.... then check the torque again.
