It's a moot point but you can make checking tappets out of a couple used ones, with decent bases, & splice them together with a tube that fits inside.
The method you used us a little fussy to get all just right but fine.
If I find any other spec I'll post them but you have it timed correctly.

: Based on the chart I made earlier, with
: 0.040" of lift on intake #1 the
: crank is at TDC and at 0.040" on
: closing the crank is at 220 degrees.
: That clearly is a lot narrower than the
: 256 duration published for the stock
: cam. That is why I questioned where
: the duration is measured between (how
: much lift to how much lift).
:
: 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,
: possibly I gave incorrect info for the
: cam you have?
: Glen
: ps- what are you using for
: "checking tappets"???
