It should be possible to fit a restrictive blanking plate, under the right inlet to the water pipe. A relatively soft alloy sheet and some gasket goo, a gasket or whatever could seal against the pipe, depending on the arrangement of the O-ring.

Tom has been working on distribution within the head space, and a plate could also be used to alter the flow relative to the two minor ports, if this might help.

Best of luck for all those involved in the project.

Trevor, with all due respect to your thinking and judgement, and we all know that your reasoning is without doubt logical. But wouldn't you think that for a high performance EG33 you should be shooting the other way around? Instead of pausing restriction on the "higher" flowing end, why don't you amplify the "less" flowing end? Your performant EG33 will require more cooling in that sense.

This not in fact a matter of one flow overcoming another flow, it is a matter of two unequal pressures, presented with a single outlet.

This is what I am thinking about, a system where you can have twin water pumps without any resistance or restrictions, each cooling one bank and both of them equal in performance to the OEM pump. This way you will cause cooling balance inside the engine.

Trevor, can you show us a diagram about this V8 you are talking about? Or is it general to all Ford V8's?
