So I am finally swapping my locked 14b with a 16g, and I have run into a couple problems:

a stud is broken off inside the head.

and several studs are stripped.

believe it or not, I didnt do it, the previous owner did, and I almost knew that this was going to happen when he told me he replaced the manifold "because it was cracked" it seems nobody knows how to use a torque wrench.

so, can I drill and tap the 8mm stud holes to 10mm?

what is the best way of going about this?

I could take the head off the car and bring it into a machine shop....it would be annoying as hell, but I could do it.
