Manifold Stud Torque

[Fillinjc]

Hi,

Installing a new intake on my 1930 coupe. Using studs and brass nuts I installed a year ago with the engine rebuild. I was torquing to 30 ft lbs. As I was finishing, the front stud began creaking to beat the band. Not even sure where the torque ended up. I am thinking to redo them using Anti-Seize. Les Andrews book says reduce torque by 45% using Anti-Seize. Torque to 17 ft lbs?

Thanks,
Jerry
