Tom, if you think you can rebuild a hybrid 3L with hand ported heads, hand cc'ed chambers, calculate your true compression ratio, hand build your own turbo system using an untried turbo on an untried engine combination successfully, then street tune it successfully with a custom made Greddy Emanage timing box (with home built inerface and injector harness cables as well), then try to make us believe you know how to read plugs?!?!?! Yeah, right!!!
j/k
If the plugs look fine in person, I tend to trust your judgement. The aftermarket replacement pistons should be fine for your rebuild. As always, we'll expect the full rundown on every major event.
