Hello
I got 3 akra 196 clone motors in a buy out. All run good. The guy told me that one in particular was always his favorite. Upon inspection I noticed that the intake valve guide does not protrude into the runner as far as the other motors. Is there a minimum length it had to be. I have one extra head from the buy out and it measures 1.240 in long. Is there a Akra minimum length? Thx
 
Valve Guide Length: 1.055" minimum ( New gauge will check proper length as well as guide location or depth .890” into port area) also checks spring pocket flatness, stock guides ONLY
