JDM F22B DOHC - Engine Internals

Hello all,

I've been running the JDM F22B DOHC engine for years, but I still could use some help locating parts.

My issue is internals. I am looking for modestly improved, streetable pistons, valves, and cams.

I can find a few decent pistons for the F22A/B but would appreciate any pointers from those who may know of options that fit the engine (I currently run 0.5mm (0.020in) oversized pistons from the F22A1 for what it's worth).
Also, I have not confirmed what valves or springs/retainers fit in this engine (tried H23A1 and they DO NOT FIT, at least not the valves for sure), and I have not found any set of aftermarket cams that are DOHC non-VTEC. I have a nice set of Skunk2 adjustable cam gears for the H-series that fit, but maybe cams/valvetrain for F/B would be the way look? Any help is appreciated!

In a general summary (for those who aren't versed in the F22B):

All components connecting to the exterior of the block can be sourced for the USDM F22A1
All components connecting to the exterior of the head can be sourced for the USDM H23A1
Anything between the block and head, well... lets just not talk about that

*Side note:

I totaled the Prelude this was in and I'm working on blueprinting and re-rebuilding to cram this into a daily 2000 civic hehe. It's not a race/track built engine though, so I just want to see what's out there and hopefully shed more light for those that have this same engine and question/s.
I've already done a rebuild with all machining and replacement (except valve train components, transmission, and crank thrust washer), if anyone has questions let me know, if anyone has criticism you may kindly not.

Kind regards
