Heads Casting Numbers

My dad called and said he had a set of spare heads laying around the barn. I asked him to get me the casting numbers off of them and this is what he sent me:

83217369 (He said the "8" could possibly be a "3")
GM 12

The trouble is, I can't seem to find out anything based on these numbers. Anybody know how to read these, or point me to somewhere where I can find out about them?

Re: Heads Casting Numbers

Google says "369" castings are a 76cc chamber head that came on a '90s crate engine.

What did you type into the search engine to get that result?

They aren't vortec heads, correct?

Re: Heads Casting Numbers

"90's" doesnt mean Vortec. Vortec wasn't available until 1996. Probably TBI heads.
