place the heads cylinder side down and spray WD-40 in the exhaust and intake 
ports. let them sit for about 15 minutes and then pick them straight up and 
look underneath. If the valves are sealing well, it will be dry around them. If 
not, it's time for a valve job.

  Didn;t you tell me to turn the heads over and spray WD 40 on them to see if 
the valves leak?
   
  What was it that I needed to do? I forgot...
