Has anyone seen a STAR mark like this on a 4.3l (or any SBC head) or know what it means? Going through a pair of 4103 TBI heads that came out of a non-running 92 / 4.3l I purchased couple years ago. Trailered it home, swapped in new engine the next week, and just now getting around to taking a look through the old engine/heads 2 years later.

No plans for them - just curios. First time ever seeing it.

General Motors used a five-pointed star as a foundry mark on cast iron components, including engine blocks and cylinder heads. The star does not identify the specific part or date but rather points to the manufacturing facility, with this symbol being traced back to the Chevrolet Grey Iron Foundry, later renamed Saginaw Metal Casting Operations.
