First the question.

Can you safely run Mercury EAC heads on a 24 stud Ford 59 block?

I have a motor that I purchased and ran in my car for a couple of years that is exactly that configuration. I was recently told that there is a water hole in the 59 block that does not line up with any water hole on the EAC heads and that this could create a loss of water. I have not experienced this, but am now wondering if it could potentially create another issue related to cooling that I should be aware of.
Any wisdom appreciated.

There is a hole in the front of each head that connects to the water pump by-pass hole in the 8BA block. The hole has to be blocked when the 8BA style head is put on the 59 style block.

Yes, they'll work, but they are low compression. EAC heads would be much better.
