Turbo Gasket

I have an F-54 block with a P-90 head. Indications are that I have an 81 combo since the Turbo is NOT water cooled. When I look at the block, I see 1 water hole adjacent to each cylinder. When I look at the head, I see 2 water holes. The Gasket has no water holes! This doesn't make sense.

Carl Beck thought that the holes might be blocked to force water through the water cooled turbo bearing housing. Since My Turbo is not water cooled I do not think that applies here. I can accept that the 1 water hole in the block is increasing flow to a degree, but no water holes for vertical water flow forces the water to flow from front to back in the block and then aft to forward in the head. That seems to be inviting trouble. Anyone with any thoughts on this??

I have a 77Block/gasket/head and it has 2 holes and all are open.

ThanX in advance.
