Yep would be much easier if new parts were delivered first, but I was just glad to have the parts supplied by the factory. But it's not that difficult to make sure that you are at TDC on compression stroke by inserting a straw or something similar down the sparkplug hole and checking if valves are closed when the pistont reaches TDC as can be seen by the travel of the straw. Check this against marking on cam gear which should also line up. I then pull the bung on the flywheel and put a mark on the flywheel that can be verified when TDC is reached again.
If the cam is install 360 degrees out, TDC with valves closed on the compression stroke is still 360 degrees out. The ONLY way to know, is to look at the cam gear on the FRONT relative to the crank position. Looking at the flywheel might show TDC, but you still need to verify compression stroke versus exhaust stroke.
