I wouldn't even consider trying to weld that.
Chances of success are minimal.
Be best to look for a used engine, or good used head and block.

Oh man, that's a tough one, problem is it will warp, and possibly also make the cylinder not round, due to the combo of both heating the cast sufficiently and the welding itself.
Being the head is gouged as well.. new engine time me thinks.

Worth a try, and mic it after, will need to be decked most likely. Since it's cheap to try, but guy needs to have good experience (old timer).
Most likely won't work, but I'd try it.
I tried to weld an orbital motor crack last year, failed miserably, no load even.

Ouch!
It had to have been pretty hot to have done that so I would suspect the head to be junk.
Since I'm thinking you need a different head I would start shopping for another engine. Spendy project I know.

Was that a turboed engine?

I don't think it got hot, just a ton of air and fuel whistling through a blown head gasket..

I wonder if they can nickasil that? I had a piston explode one time and the walls had massive gouges in them, they nickasiled that hole and the motor ran 100% after that hole was cleaned up! My head was hammered up too, but there was enough meat left to mill it down.

To nickasil stuff isn't too expensive, they somehow electroplate pure nickel to the cast with some sort of splatter method, and it is solid I tell ya! Ask if that is an option.

It could be repaired.
Looks like some of the rebuilders spray weld those types of repairs.
Either way it is a costly situation.
That engine would be a perfect candidate for a complete reman on a pallet.
Everything looks good on the outside no cracks good core to trade in.
Just put the head back on.

going to try our luck took the block to a machine shop that can weld it up and then plane it back down they say have very good success rate the head they wont weld up though they will just rebuild a different one that they have in stock.They are actually rebuilding the whole engine what every is needed. And the price quote was actually quite reasonably.

How deep is the gouge? If they just milled it .030" would it take care of it? Looks like not but pictures can be deceiving...
