what are you using to measure it and are you checking it against what ever those things are called that one uses to check accuracy ... the name slips me at the moment  I have a set of crane solid rollers that measure about .9035-.9037 so it's possible. Do you have tight bores ?

A Starrett mic and dial bore gauge.
Tight bores? In the world of Mopars, yes. Since the engine is in the car and only receiving a cam swap, enlarging the bores is not an option.
I have a forty year assortment of used lifters that almost all measure .903" to .9035" in non-worn areas. Everything I have of recent manufacture has been .9038", a set of Comps made in 2006 (a bad year for flat tappets) are .904" to 9048", some vary almost that much top to bottom on the same lifter.
I need to rephrase my question. Does anyone have a recently manufactured flat solid lifter that measures .903"-.9035"? If so, I need to know the brand. The cam makers either don't know or simply lie.

Just measured a set of B998 solid Hylift Johnsons.... .904-.9042 on the money. I think Trend has .903, but you'll pay dearly for them as compared to standard typical offerings as seen here.
