Cast iron 18 degree heads

[Jim11h]

Anybody know anything about? I've only ever seen aluminum. Seller says they're cast 393 heads and can clearly see bowtie on heads. They apparently was running in outlaw asphalt car or stock car of some sort by photo and video.

Unless someone made some steel ones in the last 10 or 12 years, all 18 degree style heads where alum including both GM and aftermarket. I also believe the GM part number was 363 not 393 but it's been a while.

Yes 363. I typed that wrong. Pic definitely looks like steel. Thought maybe make dang good sportsman limited late type motor if really cast iron 18 degree

Maybe sprayed with some steel paint to get around rules? The only steel heads that i know of close to 18 degree are the 14 degree pro action heads
