Default How many different casting numbers are there for aluminum BBC heads?
Anthony: The heads that you have are prototype (pre-production) heads. Any part numbers that start with a zero (0) or a zero dash (0-) are prototypes. I have a (0-xxxxxx) aluminum intake manifold with a winters snowflake emblem, as I am near the winter's foundry plant in Canton, OH. Don.
