Personally I wouldnt buy a GE conversion kit because they dont usually come with an oem honda/acura headgasket.
I would buy each item I needed & use an OEM honda head gasket.
Concerning 1 up oem pistons, you can use a factory headgasket.
Acura only makes 1 ls (p75) headgasket according to my books...
They would list an alternate part number for an overbore headgasket if it was needed....
