I sent those pieces of **** back. They were smaller out of the box than the lower end of the Subaru spec. By that I mean they were too undersized to put in the smallest possible Subaru block. And the company called them nominal. They refused to acknowledge this when I asked them about it. They were literally not fit for a brand new motor, much less any motor that is being honed and rebuilt. They would have slapped and smoked for sure. Crap.
