Fixed the little hole today. Went this far, figured epoxy is seriously half assing it. So I milled from the outside to get to the secondary port and the ACV port. Welded the two of them up real good, smoothed out the outside again and ported the hump in the secondary tract. All good!

I have to say this intake is some nice metal. I'm used to welding on transmission cases alot and this was a daydream. I will say it's pretty porous. It's like they used good aluminum but had somekind of flaw in their casting process.
