In all honesty, if you are splitting the bolck, why would you use stock pistons?? They are a restriction to how much power you can make due to the compression. Get a set of custom low compression pistons made, don't sidestep your build with shaving stock pistons.
Pay attention to your bottom end. Slightly larger oil clearances with a high volume oil pump and some good bearings is a start. H-beam rods and ACL race bearings is a good finish. Running a 40weight oil is also a good idea to help maintain a better oil pressure and keeping the bottom end wet.
ringlands break from detonation before they will from power

Thank you for chiming in Tom! Simply put, a set of 1100$ pistons will put this build on hold for a good two years at my current income rate. I'm not trying to 'rush' it but I don't want reliability issues either(counter-intuitive I know).
Almost every 'built to withstand xxxhp' engine I've seen needs to be rebuilt frequently. I figure, as long as everything is healthy in the engine, keep it oem spec and make it as boost friendly as possible in stock-form with 100% oe components(or as near to factory as my plans allow). If I can find them I'll get OE bearings and freshen things up and spec out the crank while I'm there.
