this can be different with different exhaust or airfilter or being at high altitude
or being at seahighth - we mesure at about 20 degrees at about 400 meters over sea!
very important:
all cams has to be closed at the end to get the right oilpressure
all cams can be used to go with distributor or airpump or whatever
so if you use for example 2 distributors, 2 holes has to be closed
if no distributor is used all 4 holes have to be closed
all cams are designed with the 18,5mm drive!
