A little update...
I finished the welding. The head was preheated and slow cooled in my oven. You should have seen my wife's face when she opened the oven to cook some pork chops I also did some rough machining and had it shaved for a finished HG surface. I went with the plan from the previous page (See Pic) and ended up creating the interconnecting oil drains to the corners. Welding this buildup was not fun due to the tight spaces and trying to get the TIG torch in there, but I managed.
One Key note is that I was so focused on the oil drains that I noticed that the crush zones on the head gasket between the back of the head and the Cylinders impeded into/near/too close to the cooling jackets for my satisfaction. So, I ended up bridge welding those as well. (see annotated pic below)
Pics after the machining will be up tomorrow. (click to enlarge)
Drilling the Oil Galleys
Plugging the Oil Drains machined from AL Rod to aid in Plug Welding
The HG Crush Zone I was referring to
One of the corner drains welded but not yet machined (very poor pic I know)

Teaser Pic. Notice the build up areas on the Exhaust side for the new Oil Drain Galley(s) interconnecting the 3 center drains to the corners respectively. Also, notice the now bridged area between the Cyls and the rear (exhaust side) of the head.
Have not finished the machining here:
- Corner Block Drains have not been redrilled
- Rear Coolant passages, not opened up yet to match Headgasket.
- Large offset front drain not remachined
- Head has not been PnP'ed yet
Before and after:
