330 Engine Studs

[Chris Coios]

A follow up note to my previous post regarding the tightening of the 8mm x 1.0 pitch nuts for the four studs that hold each rocker arm tower to the cylinder head of single cam 250/275/330 V12's: the Factory torque recommendation is 25 ft-lbs, but this can be too much, with the risk of stripping out the stud. 15 ft-lbs is reported as sufficient (but of course use your own judgement!).
