u can c my sig i get reallly hot when driving on highway specially uphills what can i do to get it down? timing? how much timing is safe to run i got stock bolts torqued to 155.... im driving up the grapevine next week with a small trailer and dont wanna catch on fire.....

 

How hot is "really hot?" I've heard 16.5* is max for stock head gasket/bolt, but I've run 17* no problem (I know it's not that much more). Also heard of people run a lot higher with no problems.
