Can't you just drill and tap the head and block to the next size up?

well there is nothing saying you cannot drill and re-tap the hole to the next size, but you should have a machinist do that.. trust me you wouldn't want to mess up.

if you are wanting to do this yourself here is a seemingly informative link: http://www.yourepair.com/2009/03/06/...d-threads.html

Helicoils are a good way to go too if you just want to replace the old thread with new thread of the same size, check them out:

edit: to answer your question the stock head bolts are 11mm i believe so you would be using somewhere in the 12mm range if you were to up the bolt to the next size
