So from here-on, verifying the cam position is best done when the mark on the 8BA pulley is aligned with the pointer at TDC on the EXHAUST stroke where you can see the valves rocking like Mart described in post #8. Here's an excerpt from Walt Dupont from a long-ago post that walks you through it...

"With the intake off, turn the engine over (right hand rotation) watch the exh. valve on no. one piston (front piston on right side) watch the exh. valve open and close, just before it closes the intake will start to open, you can rock the crank back and forth and both valves rock back and forth, both valves will be off the seat, that's called valve overlap, no. one piston should be on TDC exh. stroke. If the timing cover is on the pointer should line up with the mark on the front pulley. If the mark is off quite aways, the timing gears are not lined up. Could be the dot on the gear is punched in the wrong place. Walt"
