Casting Numbers on 78 L82 Heads

[Fred's Vettes]

Does anyone know the correct factory heads on a 1978 L82? I'm need the casting numbers only. Thanks, Fred

Casting number 462624, same number for both L48 and L82.

Thanks for the info. That's what on the motor and my research showed they were used on 305's. These also have the factory guide plates so it looks like I'm set.
