What is the best head to put on an 1996 honda accord f22b2 engine?

Hi i have a 1996 honda accord lx which has the slow f22b2 engine in it and at first i was going to do an engine swap but i have done a little research and have heard of people that put either an h22a head or f20b head on it to convert it to a dohc and have said that it has made a huge difference. I wanted to see if this is actually possible and if so what all the parts would be that i would need to do it and what all i would need to do. I would really appreciate the help hit me up with all the info thanks!
