Slant Six head swap?

No, this one is different than the Argentine head.
There were also Al-U-minimum double squish Slanty heads by Mopar, a parallel study to the 1st gen. 2.2l bathtub heads, even a turbo manny setup.
There was a foreign head I posted in Uncle Tony's Hemi-six cyl. thread, the images compressed on Me into a horizontal line, they were photobucket postings & I'm sure they expired. I may have a "cheat" to try to recover them, We shall see. I believe the poster/owner was member polara1974 on .org. Slantsixdan recently inquired if anyone had heard from them lately.
