Hey guys, getting ready to put the head back on the 450! The dealer didn't have an OEM gasket in stock so I got a Cometic. Has anyone had trouble with them sealing? I think I will be fine since these motors are studded. I was thinking about going 5 ft./lbs. over torque spec while using moly, then cold torquing them the next day. Just wanted to know if anyone had some advice? Thanks!
