I started welding up around the flange and blend into the runner, if anyone doesn't know about gtaw ( gas tungsten arc welding) or Tig (tungsten-inert gas) it's not the easiest type of welding, depending on materials being used it is more difficult or easier. Cast aluminum is among the more difficult. I've only successfully welded cast aluminum 4 times, I'll count this as 4 .
If I can figure out how to NOT dip the tungsten every freaking other minute while welding these angles I will really enjoy this.
I need to make a 5 axis manifold holder that I can rotate and flip and keep it suspended so I can rest my elbow on my bench.
I hope to have this welded and ported by the end of the week

If you are dipping the tungsten, you probably aren’t getting good enough support for your torch hand.

You have to be comfortable and have some support for the torch hand or you can dip the tungsten.

Also, I forgot to mention wire diameter. If you are trying to weld a hole or thin spot, you want to use a very small diameter wire. Every time you dip the wire into the puddle it actually cools the puddle off a bit. So you need to stop torch travel ever so slightly when you put the wire in the puddle. And keep the diameter as small as you can.

When you are welding thick stuff or you are doing something like adding materiel to an intake so you can make the port bigger, you can use a bigger wire to increase the deposition rate and make the weld time less.

Of course, it may require more amps and you are cooling off the puddle even more melting the bigger wire so you have to consider that.
