hey guys i have recently started my project EGH as i can not post on build thread ill shows you guys in flesh at some point.. hehe i embarked on a journey to find the same engine i had before the F20b... And realised it was almost impossible to track one down let alone people know what im on about...i have come to realize shortly after the purchase on my H they are available ..PM me for details.
Here is some specifications between the H22a and the destroked version the F20b



H22A

The H22A debuted in 1993 for use in the Honda Prelude VTEC as the H22A1. Versions of the H22A would be the Prelude's signature high-performance engine worldwide until the end of Prelude production in 2001. It was also used in the 1994–1997 Honda Accord SiR and 1998–2003 Honda Accord Euro-R in Japan and Accord Type-R in the UK and Europe(however different cams and a different intake manifold were used in the Euro R H22A). The H22A in the Prelude Type-S, CH6 Type-R and CL1 Euro-R came with the trademark red crinkle finish valve cover. Transmissions between all Honda F series motors are interchangeable(with the exception of the F20c and F22c, S2000 motors)

Sorry guys for information very hard to find on F20b.

The f20b will just rev that little more harder as its capacity is smaller.. the sleeves are different ..thats why when changing pistons in h22a you will need to do sum slight honing of the ports..as you don't wanna take to much of the fibre of cause then yeah will leave you in a piddle as to what to do..

Ill be posting a complete specification guide From F/H/C right after this...don't be afraid PQ welcomed lol

You should put a link to the source of information. The stuff on the H22A was lifted directly off Wiki, and the F20b info was lifted from http://www.gen5alive.com/forums/showthread.php?t=2886
