Miho1269, but I've answered this question literally dozens of times on this forum. PR CB7 and 98vtec are always there to argue me.
You just admitted to reading those things already... which is good. But what makes you think the answer is going to be any different for you?
There is even a "sticky" thread that goes into all the details of this exact question.
The only knowledge we know you have is the knowledge you share with us. When all you say is "would it be possible to build an H22 with an F22 block", we can only assume that 1) you've done little research, and 2) you aren't terribly familiar with engine building.
You wanted answers, and you got them.
I'd appreciate it if you didn't tell people how I "see things"... especially when you have missed the point of what I said entirely.
My point is that if you have to post a thread asking if it can be done, and asking how to do it from the very start of the project, the chances are very slim that you'll succeed.
I don't discourage creativity. I don't discourage risks, under the right circumstances. Bur our hobbies also involve our primary sources of transportation (for some, anyway.) That means careless advice can result in someone blowing up their only way to work.
Tell me if I'm correct in my assumptions here:
You, like Oscar, have probably never made a "can you show me how to do it from step one?" thread such as this. You went into the project with knowledge. You prepared yourself with research. You asked questions mid-project, stating what you have already learned as it applies to the project. You asked questions about a specific portion of the project, not simply "can it be done", "how do I do it", or "can you tell me everything I need to do this?"
The part I highlighted is absolutely true. I intentionally present ONLY the bad sides of such a swap. if someone has the knowledge to explain how they plan to overcome the bad sides, and explain why it's a good idea to pursue the project, then they might have a shot at actually pulling it off.
I know I've gotten myself in over my head in the past, going solely on the success (sometimes the short lived success) of forum members, and their enthusiasm. They did it, so why can't I? Well, for one, they had plenty of experience. They also had the money, spare cars, spare parts, or no desperate need for their car (all things I did not have.) I was fortunate to never cripple my daily driver for this reason... but a botched headswap done by a guy who has no spare car and no spare motor can be a catastrophe.
I've learned in my time on the forums that if 10 people politely present the negatives, and one enthusiastic member says it'll be fine... people listen to that one enthusiastic member, because that's what they want to hear.
However, if you club them over the head with the negatives, it makes them think.
I've never had a person make a thread like this and have the knowledge ready to argue each and every point I've made to the point where they display at least some level of competence in such things. I have also never had a thread where I've clubbed someone over the head with the negative aspects of such a headswap PM me a few weeks later to say "you were right, I shouldn't have done that." Why? Because I'm pretty sure after reading my points, most people don't do it!
As I've said, if it's a project car... a toy... and you have the time and money to spare... go for it. Have a blast. But if you need the car to get to school, work, or grandma's house for milk and cookies... don't risk it. Buy a full H22A and swap it in. It's MUCH harder to mess that up, and the results will be better. The process is documented very clearly on this site, as well as a few others, and it's no more difficult than following the steps.
Then, when the H22A is in, take a wrench to that F22A. Tear it apart. Learn how it works. Rebuild it, modify it, whatever... It's a spare. Something to play with. Something to learn on. If you complete it and want to try it out, you can swap out the H22A. If your efforts result in a F22A-shaped grenade under your hood, so what. Just put the H22A back in and do it again!
