[Fot] Cracked Head, can it be repaired?

[Tony Drews]

I found the source of my "head gasket" leaks - a cracked head.  It's 
cracked around the inner circumference of where it meets the liner in 
#4 cylinder.

Picture is here:

Is this something that can be fixed, or should I start brushing up on 
my head porting techniques and build another head?

Thanks, Tony Drews
Hoping to make the Mitty still...
