Which I saw in 3&5 of the stockers coming out of this motor at 88k miles. Does he de-lip, or at least mitigate lip on the ovals? I guess it could be as simple as narrowing the cone angle on the injector & running ovals.
Get with a good tuner that has experience tuning with the oval bowls, and run what they recommend.

Danville Performance is my suggestion, Mark has pushed the limit with these oval pistons
