lets see.......




the intake side.....


paper towel in exhaust port is acting as a "cork", remember these are used valves, in used seats, and stuffing the opposite port to the one being test allows for honest figures.




The numbers @ 28".......


Unported Intake -

• .050 - 58.15
• .100 - 110.87
• .150 - 146.30
• .200 - 168.30
• .250 - 180.08
• .300 - 186.65
• .350 - 191.22
• .400 - 194.10
  

Ported Intake -

• .050 - 60.02
• .100 - 114.30
• .150 - 149.20
• .200 - 177.33
• .250 - 185.47
• .300 - 192.33
• .350 - 197.78
• .400 - 202.35
  

There is a glaring error on one reading, can anyone find it??? I likely over adjusted one valve, What should it read (about/approximate)??
