Datrat_dave, If everything so far has confused you or you don't have all the fancy equipment, give this a go!
It seems your cam has similar lift & duration on inlet and exhaust. Have a look at the actual timing figures. If your inlet valve open (IVO) and exhaust valve close (EVC) figures are the same (symmetrical) or close, then this means at top dead centre (between exhaust and intake strokes) the two valves are both open and pretty well level.
ie, If your head isn't yet bolted to your block, slip both cyl.1 pushrods in and they should achieve equal lift at TDC. This ONLY works if the IVO and EVC figures and lift figures are equal.
I've used this method before and it was obvious as to what chain link the cam should be on, even though the lift was slightly different.
