Get one of these and you can use one tank.
And don't forget to add a drain bung and plug at the low point in the system.

Thanks, I hadn't considered that. I'll do that when I go back to recess the bolt holes. I think one or two heads may interfere with the belt just slightly. I also need to add a shallow channel on one bracket for the head gasket that protrudes from the side of the head. It prevents it from sitting completely flush, so I have not fully tightened it downNice job sneaking that tensioner in there.
Looks like you used a chambfer bit with bearing guide in a router. I've done the same and it works great. But the radius around the alternator fan might benefit from a much deeper chambfer to not impede airflow from the fan.
