We know there were at least two types of BTV--the poppet valve type we use and the hydraulic reaction type that Chev apparently used. If anyone knows Ed Strain or any of the other BTV rebuilders, wouldn't it be simpler to call and ask if there is any other internal differences in BTV units -- size wise, cup wise or any other wise rather than endless guessing.

IIRC, the rubber seal on the ram is backed up by a fiber and steel washer held with a snap ring in back, and of course, the ram and bore on the sides. I don't think it could be dislocated in the conventional sense--leaked past, yes.
