11:1 may be a bit high for an Accord F-series. I was think more along the lines of 10.2:1-10.5:1 ballpark. I'm not even sure if the ECU can handle that with 93 octane fuel.

Crower lists the same part number for both h23 and f22 billet rods. I figure they are the same length and that is why h22 rods will not interchange. However could h22 piston and rods clear inside the F block and give adequite cam timing in the mix? I don't think anyones ever tried.

We'll I guess I keep looking for pistons.......
