Anyone who knows the answers please confirm or deny the following:

1) The cam wheel with the "A" stamped on the front is the intake and the one stamped "P" is the exhaust and the lip on the intake wheel is at the back and on the lip is at the front on the exhaust wheel.

2) Cam timing is done with #1 and #4 at TDC and the lobes on #4 will be pointing up. I.e. #4 on compression stroke / just fired, both valves closed, number one just starting downward stoke for intake.

3) As long as #1 and #4 are at TDC it is impossible to "time the cams 180 degress out". The cams will always be back to the #4 lobes up (both valves closed) when the cam wheels are at the index (holes aligned with cam tower indexes and pointer points).

3) Ignition timing is done on #1 on compression stroke so that would be with the crank rotated 360 degrees (less static timing so ~350 degrees) from where I timed cams and the cam wheel index holes NOT aligned.

Did I get allof this right?
