What bolts to upgrade in a blown LQ9

6psi Radix (may go up a little more, if possible), 210/218 cam with 1.8 rockers.

Should I upgrade the head bolts? Main bolts? Rod bolts? Anything else? Or is it a waste of money at this level?

At 6 psi it is not necessary, but it's cheap insurance. My dad's radix'd SS ran 6 psi on his LQ9 for about 25K miles and has another 7K miles at 9psi with out even a hiccup.

Rod bolts are all youd want to mess with. But IMO that is a gamble when you do that. Id swap timing chains too. LS2 chain is a happy medium versus say a Comp double roller. Stock head bolts will be fine unless your running insane **** like Parish is.
