Timing
 

Hi people,
I just replaced the head gasket and some other work o my 1990 Civic and when reassembling it I noticed two sets of marks onthe crank pulley, one set of two and one of three notches. I know I need to install the cam with the key way up and line up the marks on the cam pulley with the head but which crank marks do I line up with the crank index mark? Any other help to get the valves right and timing would be appreciated.
