I seem to remember the Street Rod Build up Y block. Between the two middle cylinders he added two holes about three inches apart into the water jackets of the head and block. I seem to remember he called them steam holes. I see on my Best Gasket head gaskets two holes for this. Is this something I should do. If so what is the advantage.

IF you dig through the Forum archives, Richard, you'll find an amazing amount of discussion on the topic of 'steam holes'. As I understand it, FoMoCo went to using them in later year y-blocks. I decided to ask Ted Eaton what he does on the y-blocks he builds. The exchange follows below.

Hi Ted,
Question: When you do your engine builds, do you add the steam holes to the block and heads?On the performance builds, I simply plug the holes in the block if the holes are already there. If the holes are non-existent, I don't add them. On the stock builds and if both the heads and block have the steam holes, then I leave them assuming neither the block or the heads have cracks at those holes.
Ted's reply helped me. Maybe it will help you.
