    I have been searching and reading about the proper torque to use on the torque wrench for the mounting studs, head bolts, etc.. I get anything from 9-10 ftlbs up to 15+ ftlbs of torque. Can some of you pros tell me the proper amount for these motors?

    I don't know about the "pro" part, 8mm standard torque, 144 in lbs(12 foot lbs), keep in mind the poor quality of stock studs, I believe they are grade 5.8, similar to an SAE grade 3, if the head gasket is not leaking, don't mess with it unless you have to take it apart, the 6mm exhaust about 85 in lbs

    Already swapped all the studs and bolts out with the SBP hardware kit.
