theres no such thing as a non vtec h22.
preludes had an f22a1 sohc, dohc h23 non vtec, or an h22 vtec. get it right, i hate it when people spread false information on the internet.
and if you knew how to read, he asked about the h22 dohc vtec head, not an f22 sohc vtec,which would be totally pointless.
