Timing a rebuilt motor - initial settings was: My Brand New JHneeds major help

[toddguse at msn.com (Todd Guse)]

When I rebuilt my JH last year, I believe it was both # 1 valves open (not
really sure about that), dot on cam pulley lined up with top of head, dot on
intermediate shaft aligns with notch on crank pulley. Put the belt on,
tighten the tensioner until you can turn the belt 90 degrees. Turn the
engine over with a wrench 2 turns and recheck it (mine was off a tooth). 

My JH wouldn't start either after I put it in. It ended up being the check
valve in the vacuum line that goes to between the brake booster and the
intake manifold. I bypassed it because both of the ones I had were broken.
Took a day to figure this out, we checked everything because the motor had
been completely torn down. Went to a wrecking yard and got the check valve,
it started right up and ran great. It also turned my 79 into a different
car. My friends all say I drive too fast now...

Well, my Bentley is missing the motor section but I am
in the same boat so to speak; I am starting a motor I
swapped heads on and need to verify the timing between
the crank, the intermediate shaft (distributor), and
the head/ cam shaft.

I'm not at home at the moment to verify with my
eyeballs whether you are correct about the valves, but
one thing I know- you cant put an 8v cam in backwards
very easily. 

I'll see if I can put together a follow up with the
top ten (10?) tips to starting a rebuilt/retimed
motor. All contributors welcome.
