The opening could be easily sealed after the fact, I would use the aluminum based Lab Metal to do it.
Good Luck!
If you remove the vacuum pump you will avoid the freak-out when the return spring in the vacuum pump acts against the timing device's ramp and gives that "tug" as the pump's cam follower wheel rolls into a valley on the timing device's cam profile!
Thanks sixto!!!!!

UPDATE. I have removed the damaged tesioner pin, removed head bolts and raised head to drill hole from behind tensioner pin. Eureka! It was easy to drive out.
The head has 7 cracks in the combustion chambers. Cylinder 1 has no cracks.
Good news is I bought a rebuilt #20 head for 850! It appears to have been rebuilt. Now if I can get a rebuilt turbo I'll be set.
