Setting cam timing accurately without a piston to set a protractor to TDC is going to be near impossible IMO. If you temporarily drop the block on and fit No. 1 piston and rod -no need for any pistons rings- and a tappet in number one inlet, then it's a simple job. Factory cam timing has maximum inlet lift @ 110 degrees after TDC.

There are loads of Youtube etc. videos on how to set a protractor accurately for TDC and how to measure each side of maximum lift to get the timing spot on. It's OK to run the cam a few degrees retarded in a light special as you will get more top end power. Run it advanced and the car will feel dead. I always "dial in" cams, not least because after 80+ years, you can't be sure that the gears you are using are a factory matched pair even if they do have the marks on them.
