EFI powerheads on Optimax Mids
I'm putting my 3.0L 225hp EFI powerheads on Optimax Mids and noticed that the Opti's mids have two extra ports, drilled/tapped, on the port side of the adapter plate that were not on the EFI mids. They look like they're just extra water fittings, but I want to be sure that I can plug them off without a problem. Can anyone verify what these extra ports are for? Your help is greatly appreciated.

One is for water to the compressor, the other is an over pressure dump for the air rails.

OK but can they be plugged up or do I need to make a custom outlet for them? The EFI powerheads don't have fittings to accommodate the extra ports.

So no one replied on here to this, but I did find out that yes they can be plugged safely and the Optimax mids can be used with the EFI's powerheads.
