At what boost level should you start thinking about upgrading the head bolts and head gaskets
I have an s/charged LS2 524rwhp @8psi.
Doing my homework before ramping boost up to about 13-15psi and installing a snow water/meth kit.

 

Some people seem to be able to go to 15+psi with stock bolts and gaskets and don't have issues. And then others have issues at under 10 psi. It's hit and miss. But at 15psi I'd definitely recommend studs and gaskets to be safe.

 

Do studs and you'll never have to worry about it. Worth the piece of mind if you are already thinking about it
