Many of the holes in the Outfront deck plate and head gasket do not line up. I'm not happy about it and I'm debating going another route.
the holes in the EJ22T block do not line up with the current AVCS heads well, and cause cooling issues. people associate this issue with closed deck in general, when they hear closed deck they automatically assume overheating.

the outfront block has not shown to have any issues, it HAS been run in road racing and time attack applications in the subaru platform with no ill effects.

dumping a motor and going a different route based on nothing more than an educated guess is a little over the top.

I would be more than willing to bet that outfront has collected feedback from their customers on the cooling performance of the closed deck motors. they are on the 3rd version, if there was cooling issues don't you think they would have addressed it?

If you ask, they will be happy to share with you many improvements that have been made, one thing that was under heavy research was the cooling performance, that is a big player in the chosen thickness of the closed deck reinforcement.

others chose to go larger assuming its "better" when discovered thicker actually causes cooling issues.

the ports are barely blocked. given there is more than none at all but its hardly measurable.

why dont you try running the S&R closed deck, maybe it will help your cooling issue
