I am not using special checking tappets. Don't cringe but I am just using regular tappets. They (and the block) are fully cleaned and lubed only with WD-40 so they slip easily in the block with no sticking. The pushrods are oriented vertically above the tappets with the indicators positioned with radiused end tips resting in the pushrod cups. I have kept things vertical and inline so I am not worried about cosine errors. I could make a pair of aluminum rods to extend the tappets straight up out of the block but I really don't see those changing the measurements I have made.
Since I paint marked the old timing components prior to removal and was able to put things back "where they were", I am comfortable setting the timing to match using the new components. The engine ran well before timed like this and it should run well again. If for some reason it doesn't... I can always pull the timing cover off and set by overlap.
Thanks again for all the guidance. It really is appreciated!

: I don't think there is much doubt that
: you have it timed correctly, going by
: lobe center and comparing old parts.
: What you might consider doing is
: setting it by LC, and then just check
: the event timing. Set it, indicator on
: #1 inlet & zero, rotate crank until
: .040 shows on indicator, inlet starting
: to open, rotate until it's closing and
: indicator is again @ .040, just about
: closed.
: Let's see what those numbers are,
