Re:z6/y7

is the timing belt on or are you just spinning the cam on its own? as long as the timing isnt off like a million degrees, there wont be a problem. there is supposed to be resistance when you spin a motor as long as it has compression

if the timing belt is off then the valve will stays at whatever position it is no matter how you turn the crank.
it IS going to hit the valve.

align the cam and the crank then put the belt on .

Re:z6/y7

oh when you said you were trying to do the timing by turning the cam...
if it is hitting the piston, then turn the crank as well
you have to turn BOTH of them get it align, not just the cam
