Main Studs??

Just cause you have switched and got away with it doesn't mean that is the final answer. When you add studs to the mains why not have it checked after torquing the mains. Cheap insurance I'd say.

Of course, you still have to check clearances, and for distortion.

On the numbers, 9 out 10 blocks will 'not' be affected.
