If you want it to be a more reliable b20 or LS/vtec then use a GSR head. If you wanna keep it relatively stock then do a poor man's type r. With the pmtr you use the type r mani, throttle body, cams, valve train, etc...Which makes for a decent set-up stock. If you have any intentions of building it then just do the ls/vtec and get the power you will really be wanting.
