Porsche Crest 911 camshaft timing

ok, the left camshaft was setting as per Mr. Wayne book
After I finish setting the LEFT side I turn clockwise 720 degrees to double check the Left side and is OK.
RIGHT SIDE
Now I install the Rocker for intake valve for piston #4 and adjust the valve and install the PIN.The right 930 mark is downward then i install the gage. Then i turn the pulley until it reach 1.26 mm for overlapping. this happen in the first 160 degrees. Now remove the PIN and continue turning the pulley until reach TDC Z1, then install the PIN and Adjust the bolt. Now when I turn the pulley the piston #4 is in upward movement and the intake valve is in downward movement and one hit the other.
If I don't remove the PIN after reach the overlapping point then I can continue turning the pulley without problem. But I don't know if i the final adjustment was not done the cam is in the correct setting.

WOW!
Put both of your rockers in and set them.
930 numbers are up
pin both sides and run he bolts in to keep the drives from falling off.
install the dial guage on the left side
360 degrees, set the left cam to 1.26 +/- .1
720 degrees to check setting
dial guage on the right side
360 degrees pin to match the 1.26

this side might take longer because you might have to move the chain on the gear 1 tooth
match the 1.26 and check at 720 degrees.
Lock it down
