yes, they will fit. BUT the h23 pistons IIRC have pressed in wrist pins and the h22's have floating wrist pins. I believe you could take out the rods and have a machine shop mod them to accept a floating wrist pin, if thats even necessary.

 

those pistons have a different compression height so the h23 pistons may sit slightly below the deck.
since your boosting this would be perfect to run more boost safely you compression might be 9:1 i am alittle unsure tho

 

h22a4's use floating wrist pins.
