I too have rebuilt/resealed many (maybe hundreds) of boxer engines over the past 23 years. I don't hear any talk about the head studs being stretched. The heads are held to the block with very little torque, and the hardware integrity is very important. Just compare a new stud with a previously used one, maybe on that has been torqued 2, 3, 4 or more times and it's obvious that they do stretch. Also, sealer on these head gaskets is very important, I use perm-a-tex ultra grey and have never had a problem. Ever. But be very careful not to use too much. This is not a case of lot is good, more is better and too much is just right, like my fathers view on horsepower. On the top of the block I use the same ultra grey. Be absolutely certain to clean, clean, clean the sealing surfaces, use alcohol base cleaner or something that won't leave a residue. I'm sure this has been bounced around plenty, so forgive me for the broken record... That's my 2 cents on the leking head gasket talk that seams to haunt the list.
