... you just want to make sure you line things up to where the dist is either at TDC on compression of #1 cyl, or align to TDC and compression stroke of #4 cyl. If you have the valve covers off adjusting valve lash, it's easy to watch the pushrods go up and down and figure out whether #1 or #4 is on its compression stoke when the timing mark on the harmonic balancer is lined up to "0" on the timing scale. And of course, point the rotor to whichever cyl you line up to, #1 or #4.

yes, helps quite a bit thank you. though i wish i could be more confident that i am at TDC-compression #1 cylinder. i had a very long pencil down through the #1 spark plug hole as i turned the crank. pencil rose as the timing marks aligned, and the rockers were not 'in motion' during the final ~25 degrees of the rotation. i took this to be the correct position. but if this is not correct, or if there is a way to 2x check, i have not put the rocker covers back on yet.
