2g pistons, 1g rods

[blue92laser]

I was wondering, do u have to bore out the 6 bolt block to get the factory 2g pistons to fit?
Do the factory piston rings work too...or would i have to replace them with something else?

I just honed and used OEM rings to built mine. Should be fine as long as your block is not scratched.
