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.

Re: Heads Casting Numbers
"90's" doesnt mean Vortec. Vortec wasn't available until 1996. Probably TBI heads.
