Hi

While reconditioning a 1098 head, I've managed to snap one of the studs which holds the Inlet manifold on. Damn!

In case I need to drill and tap it, does anyone know the thread size ?
The thread that goes into the head is the same pitch etc as the one poking out onto which you'd put the nut.

thanks in advance..

Doug
