I run 30.5psi with 35r and meth with stock block with no issues. Then again I only use it when I need too. No dyno where I live so no real numbers either

The psi is not the real risk...Just make sure you have a great failsafe in case your meht injection fails....Plus you should have access to your turbo maps to determine optimal boost...

Headstuds have nothing to do with cams.

i think he is worried about stretching the stock studs and blowing a headgasket.
