Yes, it goes a little deeper into engine building than most ever thought of, but we've discussed the importance of knowing what your valve timing is and not trusting any so called "timing marks" to get it right.

Went back and reviewed your cam timing thread Jeff - had not picked up on the drilling of two extra dowel holes in the cam drive sprocket with the sprocket rotated on to the next bolt hole line up.
As you say "Incredibly simple"!
