Do you guys know if we can go as high as 115 ft/lbs for tightening? Running a high compression (11:1) and high boost (20+). On 25 psi, it looks like my car is getting symptoms of HG failure or lifting heads as it's pushing coolant. IIRC we got them at 105 ft/lbs now, but wondering if we can tighten higher. Granted I'm also running a Cometic HG, so that may have took a crap as I've heard stories about them before.
