help/suggestions on prelude swap

i have a 91 prelude with an b21a1 engine. im wanting too put an h22a engine in her, but im not too sure if it would be worth it. i was just wondering if anyone has done something along these, and if they had any trouble doing so, what were the problems. and did it take forever too right the wrong and all that stuff. help will be muchly appreciated. thanks

Stick with a B series, the H series is too much trouble on a third gen.

i've heard that theres not that much problems. but what would be my main concern if i went through with it?

to be honest im not quite sure what the headaches are as I have yet to do or be apart of one. But a while back 2 friends of mine dropped in H22 in a 90 or 91 prelude..these guys are not what i would call experts by any means so I dont see any reason why you and some buddies couldnt do it..but thats the best advice i can give ya...sorry
