The crank rotates 2 times for each revolution of the cam.
I am not sure what work you did on the car.
Did you line up the timing marks of the flywheel and the cam sprocket when installing the cam tower?
Did you verify and lock down the flywheel with both timing marks on the flywheel and cam tower synchronized?
Can you verify they are still synchronized?
If you answer NO to any of the tope 3 questions you may have bent valves.
1 more question. What method did you use to gauge the tension of the cam and balance shaft belt?
Please report back.
Speedy
