yes, u'll want to use 4th gen h22 pistons though, 5th gen are floating, and jdm h22 pistons will give you higher compression than usdm h22 pistons, but both will give higher compression than your h23 pistons

Just curious.... what type of piston to valve-clearance does this certain set-up give?
Wiseco has a 88mm h23 piston which is actually a TRUE h22a piston.... the piston actually stuck out of the deck by 25 thou.

ill let you know when i get the crank in, im using an h22 block, jdm h22 pistons, f22b crank/rods

The piston to valve clearance on my engine that is effectively an H23 with H22 pistons sticking out .042" has plenty valve clearance even with large nonVTEC cams. Just be careful of retarding the exhaust cam.
And the H22block with F22B crank and rods IS for intensive purposes a H23 block. Same deck height for all F-series sans S2000 engines.
