2.3T oil leak at cyl head: cracked, fixable?

Since I rebuilt the 2.3 motor in my turbo coupe I noticed I had an oil leak since I have a nice sized puddle in my driveway now and I can clearly see oil at the bottom of my bellhousing, oil pan area.

First thought was the rear main seal or my oil pan gasket since I hear it's hard to have a leak free 2.3t engine hehe
I was definitely bothered by this since I replaced every gasket on this engine and I took extreme care of installing the rear main seal and oil pan just to avoid this.

Tonight I thought I would take a look at the upper end of the motor to see if there was a possibility it could be something else and sure enough I seen it was coming from the turbo oil feed, oil pressure switch area and making its way down to the bellhousing.
I dialed it down to the oil hole on the head or the stinger oil feed T I have installed. I removed it to see if anything was up or if all it needed was some Teflon tape or thread sealant and found out the oil hole on the head has a hairline crack. I put some Teflon tape on the T and reinstalled it hopeing it would pass up the cracked portion on the threads on but no dice, still leaks.
I have another good head I can put on the engine but can the crack be fixed by welding it or something or it trash now?

I'm just glad I don't have to pull the engine or tranny to fix anything on the bottom end
