the only difference I can find is the placement of the oil control orifice. On the VTEC it is on the head while the non-VTEC is located on the block when you remove the head. If the blocks are all the same why would Honda go to all the trouble to stamp them differently? What would be their advantage. I know the SOHC VTEC is F22B1, the SOHC non-VTEC is F22B2, and the JDM DOHC non-VTEC is F22B. I hope this head change is as easy as it seems. I have procrastinating for about two weeks.
