I just find backwards easier for me and my TR3A. To go backwards, I just
push on the edge of the hood opening and watch for the valves to move to the
next position. Harder to get lined up for a good push against the front
apron, and my right arm is stronger than my left. Or if it's stubborn (like
when I had the 11:1 head on it), I can wedge my leg against the front bumper
and move it that way.
Purely personal preference and convenience, certainly not the only way to do
it. I use 4th gear, so the same gear ratio either way; and watch the valve
train move so I don't care about any slack in the timing chain. Rather than
using the "rule of 9", I just turn until both valves on a cylinder are open,
and adjust the opposite cylinder (in the firing order) since it's valves
must both be fully closed.
