MBHD,
That is the way I also do it. It is so easy to learn this method. And yes, it does work with big cams too. It is easy to see when the exhaust rocker arm is closing and the intake rocker arm is opening, and when the two "pass" each other and are on a parallel plane. That is when TDC occurrs on the sister cylinder. With this method you need not mark the damper - heck, you don't even have to look at the damper - just watch the next-in-line cylinder for rocker arm movement.
