hello!
looks like some one is trying to explain us what valves looks actually and where they are....
@blind...bro we are talking about I-dsi engine...its 8V...the engine you are talking about 16V is Civic Exi or Vti VTec engines...they have 16V....don't belive us...get some i-dsi open the tappet cover and see yourself.....might be you are not counting 8 plugs along with 8 valves that makes actually 16 
Thanxx
