I need a little help with this, I'm trying to compare the D16 valves to the D17 ones to see if they're interchangable (the springs and retainers are, which leads me to believe that the valves may also be.) There may actually be more liklihood of the 'Z' head valves fitting than the 'Y'. Not sure if theyre different, but the D17 head uses the D16Z headstuds, etc...
Below is the specs from the honda manual, can someone either post the same page from the D16 manual or confirm that those numbers are the same? It would be a big help. Thanks
