My reference for a OEM piston would be a K24 which yields tolerable compression for pump. I suggested H22A piston because dome tom dicken harry may wanna use that amount of compression on vtec killer cams or pro3's with big primaries and race gas. I wouldn't do too thick of a headgasket coz it reduces quench and exposes the gasket which is to why it eats the gasket.
87 x 89 is ok on a b20
87 x 92 is crazy haha.
But my setup would be 84 x 87.3mm on a B18C. Might be next year.
Regarding the k-series oil pump issue. If you search on honda-tech, one of the company did a research on the oil pump and actually modified it and tested it to be reliable at high RPM already. Heck, they even put an article on what needs to be done.
