Well searching old threads didn't bring anything up - my son and I are working on his 83 Shelby clone, A465 trans locked a bearing so I rebuilt the trans and he's getting ready to put it back in. Figured he'd open the motor (2.2 NA, non-shelby) and replace the 30 year old gaskets and seals, 43K on the motor, slight seepage. When he went to pull the head he broke 2 of the bolts off - the 10mm head bolts. One is flush with the top of the head, looks to be coked in with burnt oil, #4 back of the motor by the trans. The other broke off further down and is on the back side between 2&3. The head is stuck fast to the block still, I'm going to work on it this week.

Back in the day I tore many 2.2s and 2.5s down for parts and never had this happen.

Any tips or tricks?

I'm hoping the one is not flush with the block - I've seen the washer/Nut weld fix but never tried it.... Maybe this will be my first attempt.
