what kind of pressure can i run with a stock gasket and 12mm studs without having problems? i also plan on playing with the timing advance, i know this also affects cylinder pressure, so what is a safe overall pressure with a setup like this.

 

well everybody says 55psi but before my orings i would push 65psi,, with the timing jumped a tooth.

 

really??? i was under the imperssion that 45-50 psi was a some what accepable with stock bolts... the $450 price tag, and the time involved really doesnt seem worth it for the gain

 

doesn't everybody use 14mm studs?

 

No you have to drill and tap the block for the 14mms
