The GM casting #462624 (often referred to as "624") with steam holes was specifically manufactured for the 400 cubic inch (6.6L) Small Block Chevy engine. While the 624 head was used on millions of 350 engines from 1975–1987, the version with factory-drilled steam holes was only fitted to vehicles equipped with the 400 Small Block, which was produced from 1975 to 1980. Here is the detailed list of models and years that utilized the 400-specification (steam hole) 624 heads: These heads ARE interchangeable with #624 6 hole 350c.i. heads. Compare your heads to these to ensure the correct match.
