  NOTES:

  Valvespring Installation Height:
  

• Initial Measurement:

  #1 intake = 1.798" #1 exhaust = 1.800"
  #2 intake = 1.800" #2 exhaust = 1.803"
  #3 intake = 1.797" #3 exhaust = 1.806"
  #4 intake = 1.797" #4 exhasut = 1.802"
  #5 intake = 1.805" #5 exhaust = 1.798"
  #6 intake = 1.805" #6 exhaust = 1.804"
  #7 intake = 1.797" #7 exhaust = 1.804"
  #8 intake = 1.793" #8 exhaust = 1.797"
  
  After removing shim in #8 intake: 1.807"
  
  The difference bewteen the highest ( 1.806 ) and lowest ( 1.793 ) is .013". CompCam allows
  for +/- .020" but I removed the shim on #8 intake and achieved the following size of 1.807".
  The new delta is bewteen 1.807 and 1.797, which is now .010".
  
  
  
  

• Valve-To-Piston Clearance:

  Intake measured at approx. .180"
  Exhaust measured at approx. .150"
  (both measured using modeling clay method.)
  
  
  

• Camshaft Endplay:
  0.004"

  Camshaft Intake Centerline:
  Cam-card specs: 108°, actual 107.5
  

• Combustion Chamber Volume:
  
  #1 - 61.2cc
  #2 - 60.9cc
  #3 - 61.0cc
  #4 - 62.2cc
  #5 - 62.0cc
  #6 - 61.0cc
  #7 - 61.0cc
  #8 - 61.0cc
