That should give you enough to dig into the story.

 

prob 'some what' later version -that ad was in 1960 hrm ....

 

There was another post here asking about early hemi heads. It ended up being Ardun heads. I didn't bother posting it.
Ardun heads are aftermarket replacement heads for flathead Fords. That would fit the time period.

I’m looking at that photo of the ad on my iPhone, am I wrong or does it say DeSoto heads? And also, can anyone make out the sellers name?

 

Yes Desoto. Jack Myers

 

Thank you. Now to search for Jack Myers, racer.

 

Kinda? It's tough to read.
Searching DeSoto aluminum heads came up with this
https://www.jalopyjournal.com/forum/threads/desoto-hemi-q-a.700063/
which points to the Hemi Index here and
https://victorylibrary.com/mopar/desoto-c.htm
and a bunch of much more current stuff and ads.
I guess it could be a small thread into something done back then, but with what little I know about Donovan history, and drag history I doubt there were any readily available aluminum Desoto Hemi heads in 1960. The Chrysler was the more dominant engine used unless it was size restricted by class.

EDIT: If you are going to track this down, make sure you use Torrance, CA too.
