Get another motor, you can try some block fix product. I've had luck with some, but its by NO means a permanent fix, it may get you by for a month or several months, or it may not work at all-depends on the breach
But as the others have said, it would be far cheaper to replace the motor than to have that one fixed. 1) because the block has to be removed anyway
2) machine work is expensive
3) then all the gaskets needed -head gaskets, timing cover gaskets, valve cover gaskets, plus new head bolts-
4) then finding someone that has the set-up tools and knowledge on how to time these motors (LOL good luck)
5) then reinstall
I just picked up my new motor a few weeks ago for the same reason, I breached my block at the #7 cylinder exhaust port and coolant was weeping out by the header on the driver side head, and oil was weeping out of the #3 exhaust port under the pass head
My last mark breached coolant into the #7 and #8 cylinders, I added Barrs Leak BlockFIX to that ones coolant and got another 3-4 months out of it before I had to swap blocks
