Opera guy, I have a manual if you want to borrow it. Most 8 mn nuts are torqued to 14.5 lb ft in my manual but I know to watch out on the exhaust studs. The other 8 mm bolts could be up to 18 but maybe 14.5 would be better. I never read the torque on the nuts for the vavles. I just tighten to what I think will hold them. Maybe 12-14 ft lbs. I hope this helps. Again I have been wrong before. Mark
