Inlet backwards, exhaust forwards work TDC and cylinder firing.

This shows the cam at TDC, just about to fire the spark plug on cylinder 1. The exhaust cam lobe points in the opposite direction.

More or less 180 degrees. If you look here, you can see that there is a line/mark on the cam fasteners that aligns with a dot marked on the cam (you can just see the dot on the intake one in this picture). This is the position for TDC/ cylinder 1 spark firing.

There will be a spark at both cylinders 1 and 4 at just before TDC on every revolution of the crank (wind the crank back slightly from TDC and you will see what looks like a box on the edge of the flywheel, this is ignition timing mark) due to this being a 'wasted spark' ignition system. Cylinders 2&3 both fire at 180 degrees from that.
Ignition timing isn't adjustable.
It sounds like you are setting the cams right.
