Yes. That is it! Thank you.I think repeatedly threading a nut on a steel stud holds up better than tightening a bolt into an alloy head. I wouldn't change them.
The usual suspect is the front right bottom one. I think red locktite to keep it from turning would keep it from stripping, on the theory that it has to turn before it can strip the threads it's in. It could still just pull the eff out but it would take a lot more force. Also, you have your choice of gasket or big o-ring on those. I think the o-ring takes less torque to get sealing.Mind yer torque specs and you should last without stripping 'em outta the head.
