You guys are correct. The holes are there both for cooling and to support the water jacket core during the casting process. Same with the "Freeze Plugs." Those holes also are used to allow core gas to escape while the metal is liquid. The binder, that holds the core together is usually a plastic of some form. When you pour 2500 degree iron around it, the binder burns off creating a lot of smoke and gas. You don't want that in the metal, so it needs a path out through the core.

Just a guess on my part but those holes in the deck surface and the "freeze plugs" are there to remove the core sand after casting/pouring as well as forming coolant passages.

Needed for core support during the casting process.  Pegleg is our reigning expert, he can probably expound on this.

EJ:

The gasket is supposed to block the water holes in the front to force the water to flow to the rear cylinders.

Looks to me like the gasket was blocking the water hole in the head. Is it on backwards?

Yes, I had the heads cleaned, some new valves, and head was shaved.  I'll try advancing the timing.  I'm also wondering if I need a 4 row larger capacity radiator?

Thanks so much for your suggestions.  Please keep senting them.

Gary ,

 Did you have the heads shaved before you replaced the head gaskets ? Maybe one of the heads is bent from over heating . Also ,did you check to see how square the block is ???You can have your radiator pressure tested with an added chemical to see if any CO2 is entering your cooling system . Any good radiator shop should be able to help .Hope this helps
