I did it to the head... less wiggle jiggle, less chance of gooping all over... ...

PS... keep track of where each bolt goes...  but, if you get mixed up,.. pop them in to all the holes before install,... and if you have them right, they'll all be sticking out the bottom about the same length...

PSS... one of the bolts (can't remember exactly) near TDC of cover, needs to be inserted in the cover before you put it in the frame... assuming you're doing this while the engine is in frame...

Go to tech section and print out bolt pattern, glue it to a box and use it.  One bolt HAS to be in cap BEFORE you install it. I used Yamabond 4 for the head to cap seal on recommendation of Suzuki shop, but others use Suzuki goop with good results. One of the valve rocker shafts can slide over in the head cap and cause a bolt to not go back in the cap. Be sure the valve rocker arm shaft are all the way into their bores. Study tech section well before starting and keep it clean. Not a hard job. Just go slow and take photos if you can't finish in one sitting or can't remember where things go.  

you don't want hard stuff, that's why it's so hard to clean up.
to want RTV 500° or higher
i usually just scrape it off with a wood chisel cause it offers more control of the sharp edge.
but a dremel with a nylon brush works
or strippers will take it off chemically.
