If all H&F series engines have the same deck height, what does that mean? That means that you can put F23 parts in an H22. Or H22 parts in an F23. Or H23 parts in an H22. Or F22 parts in an F23..... You get the idea.
Why does this matter? Unlike B-series engines, which all have different deck heights and means they must use different length rods whether you're building a B16, B18a or B18c. In the H&F Series world, since the deck height is the same for all H&F series it means that you can swap rotating assemblies easily. Just match your crank to your rods and pistons, then you can put that rotating assembly into any H&F series block. For example, if you have an H23 crank, rods and pistons, but you don't have an H23 block don't worry! You can install that assembly into an F23, or and H22, or even an F20b. You'll just need to consider the bore size and the main journal diameter.
MAIN JOURNAL DIAMETER: Of course there are exceptions. While the more popular H&F series have 55mm mains, some of the early 90's blocks use smaller mains. Here's the list of main journal diameters by block:
H22A = 50mm
H22A1 = 50mm
H22A4 = 55mm
H22A4 = 50mm (1997 Only)
H23A = 55mm
H23A1 = 50mm
F20A = 50mm
F20B = 55mm
F22A = 50mm
F22B = 50mm
F22B1 = 50mm
F22B2 = 50mm
F23A = 55mm
The H22a1, H23a1 and F22 blocks have 50mm mains. These are the engines in early 90's Preludes and Accords. (they're easily identified because they're closed deck, see picture below). These engines will only accept cranks that have 50mm main journals. So you won't be putting F23 rotating assemblies or any 55mm H&F series rotating assemblies into your engine if you have this earlier version of an H22, H23 or F22. BUT you can swap F22 cranks into your early H22 or H23 and have a sleeper stroker!
BORE SIZE:
H22A block = 87mm/3.425
H22A1 block = 87mm/3.425
H22A4 Block = 87mm/3.425
H23A block = 87mm/3.425
H23A1 block = 87mm/3.425
F20A block = 85mm/3.346
F20B block = 85mm/3.346
F22A block = 85mm/3.346
F22B block = 85mm/3.346
F22B1 block = 85mm/3.346
F22B2 block = 85mm/3.346
F23A block = 86mm/3.385
For more information, the holy grail of H&F Series information is on Honda-Tech.com and shoutout to @Hondaccord the user who put together the list.
*There are other considerations, like which cylinder head you plan on using. I'm gonna keep this one short like most people's attention span. Contact me for details on cylinder head compatibility.

My testimony on how I became an illuminati member. My name is Foley and am 39 years old, I’m from Austria I want to notify the people who want to join the great illuminati , on how I was helped by the Great Illuminate World secret society in regaining back my business position after been sacked for about 5years and six months. I have been in pains and troubles ever since I ,was sacked from the company where I work, called ‘ESA Deposit Insurance corporation’ as an agency executive. I have been hopeless, financially down through out those years. But one day, as I was browsing through the Internet, I came across the post of the Great Illuminate world society saying you can be famous, rich and successful in life by been a member of the great Illuminati member, immediately I contacted and I explained everything to them and they recommended me and helped and I pay for the Initiation Fee which will be used to initiate me, and I was initiated to the great illuminati world secret society after and also they gave me all the guidelines and told me their place worship. With the help of the Great illuminati world society I was able to go to temple and there I was initiated fully as a complete Illuminati member. Surprisingly 48 hours after i was initiated, I receive a call from the company that I have been accepted back again as the agency executive of the company at first I was shocked and surprised when the brotherhood offered me 500,000.00 Euro a car and house with other things that has changed my life for good regain myself, WhatsApp Mr. berry castle on +1 (779) 324-0633 or email illuminatiusatemple666@gmail.com
