The accord engine he has is a f22b1 vtec SOHC engine a H23 or even H22 are DOHC and the block are just a bit bigger and shape different. I done alot of research on this because I wanted to do the same swap but like blackmagic said you can do anything with money but for the price youll pay the swap series heads might as well just pay to do the whole swap and get a stronger bottom end for that head.
