Default Building motor, bigger than 100mm pistons? + where to get o-rings

My current stage 3 Raw/Axis block is being rebuilt due to oil consumption. Machine shop say the hone was far too aggressive and prematurely wore the pistons and rings. Problem is the bore was already 100mm.

Are there 100.5mm or 101mm pistons readily available?

Ive already got head gaskets, and an oil pickup. I need to get intake mani gaskets. Any other gaskets I will need?

Also, where should I get an o-ring kit? the dealer/subarugenuineparts?
