So I've rebuilt my smallport got it installed and running.
Now I want to get the most out of the after market camshafts.
But I'm just not sure how to go about timing them precisely.

From what I've read, I need a timing disc (bolted to the crank shaft)
with a pointer (bit of wire?) to find TDC using a dail guage down cylinder #1.

Now at TDC the intake and exhaust lobes over #1 should be pointing at each other?
And when I turn the crank over by 110deg clockwise, the intake valves should be fully open.
And then the crank gets turned over by 110deg anti-clockwise from TDC and the exhaust valves should be fully open.

Okay so here is where I'm lost... Where does 110deg come from? Why is that the figure we're looking for?
What happens if the valves arent completely open, or have started to close at this 110deg mark?
Is this where adjustable cam gears come into play to rotate the camshafts so the valves are fully open?


If it helps.. the cams are HKS 256deg 8.1mm lift, the head has been shaved and I'm running a thinner headgasket.
