Water Passages don't match Head Gasket

I am rebuilding a 429 I got out of a Ford Torino to put into a project 68 F-100 shorbox pickup. The block and the heads have elongated water passages on the sides and tear dropped shaped passages on the top of each cylinder that are not cut out in the head gasket itself. Is the gasket for the 429 meant to be a flow restrictor for water passage or could it be that someone has machined in extra cooling passages? My parts guy and I have been trying to find a gasket that matches the cooling port pattern with no luck.

Any help?

The block - D1VE 6015 AA
The Heads - D0VE-C

I know this is a old post I am replying to but I just ran into the same problem. I have a bad overheating probelm on my 460, I have tried all of the normal things, new radiator, water pump, thermostat, etc. I pulled the heads today and it looks like some of the water passages are covered by the head gasket. Same as you described. Just wondering if you found out a correct head gasket that allowed all of the water passages to be uncovered. Thanks.

Here is a picture of what I am talking about.
