double nutting could work.
one trick I like to do once is in a while is take a 13mm hex nut ..
cut a slice down through it from one side with a hack saw.
then you have a 'thread shaped thing' you can clamp onto the threads
with a vice gribs and apply serious force on the threads without
damaging them..
or perhaps this method combined with double nutting.
I prefer studs for two reasons..
one, if a nut is rusted onto it ....it's very easy to heat the nut to
remove it.
( if a bolt is badly stuck in the head.....heating helps a little, but
not that much really. )
I also don't like screwing a bolt in and out of the head ..
threads wear,. someone may put in too short a bolt etc.
Granted...you can't sneak in an exhaust port gasket if you need to ,
with studs.
studs are generally a stronger way to mount things..
like wheel mounting studs are better than wheel mounting bolts, for
example.
Same way with cylinder heads studs versus bolts.
I also notch out the top of the tabs that are at the top of the push rod
covers, so those are easy to move just by loosening the nut with washer
under it.
Especially the left, side, like if I want to get to the oil pressure
switch area.
and sometimes...if there is only one tab at the top of the push rod
cover ....that works just fine in conjunction with the two lower
mounting bolts.
I like things easy to work on. I don't leave off important things at all..
but when practical...I make 'em easier to work on ...like on would on a
race car ..where it's worked on all the time.
